Mac Mail: Unable to Verify Account Name or Password (2026 Fix)

"Unable to verify account name or password" means your email provider refused the sign-in attempt your Mac's Mail app just made. The password itself is often fine. The usual culprits are the wrong account type in Mail > Add Account, a provider that no longer accepts a typed password, or a password that needs to be an app password instead. Sign in to webmail first, then fix whichever of those applies.

The message usually shows up at the worst moment: a new Mac, an address you need today, and a password you know is right because you just used it in Safari. That combination is the clue. If the same password works in a browser and fails in Mail, the problem is how Mail is asking, not what you typed. This guide covers that error specifically, at setup and when it appears on an account that used to work, provider by provider.

What "unable to verify account name or password" means

The error means Mail reached your provider's server and the server said no to the sign-in. That's different from Mail not reaching the server at all, which produces timeouts, "can't connect" messages and a lightning bolt in the sidebar; for those, our guide to Mac Mail not connecting to the server is the better starting point.

Apple's article on Mail asking for your password lists the reasons a provider rejects Mail: the password changed on another device, the provider wants a different kind of password (an app-specific one), the account was suspended, or the provider changed how it lets apps sign in. In practice, it comes down to one of five situations:

Step 1: Prove the password works in webmail

Signing in to your provider's website with the same address and password tells you in a minute whether the password is the problem. Testing with webmail is one of the checks in Apple's own troubleshooting for this problem.

1. Open Safari and go to your provider's webmail (gmail.com, outlook.com, mail.yahoo.com, icloud.com/mail, or your work's mail page).
2. Type the password by hand rather than pasting it, so you know exactly what went in.
3. If webmail refuses it, reset the password on the provider's site, then come back to Mail.
4. If webmail asks you to confirm a security alert, accept new terms or verify your identity, finish that in the browser, then try Mail again.
5. If webmail says the account is locked or suspended, only the provider can lift it. Apple's article says the same: contact your email provider.

Before I touch a single setting in Mail, I run this check. If webmail lets me in, I know the password is fine and Mail is the part to fix, which spares me resetting a password that was never broken and then having to update it everywhere else.

Step 2: Pick the right account type in Mail

Mail on Mac signs in differently depending on the provider you choose in Mail > Add Account, and the wrong choice is a common cause of this error. Choose the provider by who runs your mailbox, not by what your address ends in. Apple's guide to choosing the provider is specific about addresses that look like one company but sign in through another:

Two notes from Apple's page are worth knowing. A Comcast address that hasn't been moved to Yahoo still goes under Other Mail Account. And if you picked the wrong option the first time, take that account out of Mail before you set it up with the right one; otherwise Mail may tell you the account already exists when you try a second time.

To add an account with the right option, per Apple's setup guide:

1. Open Mail > Settings (or press Command-comma) and go to Accounts. If you already added the account with the wrong option, select it and click the Remove (minus) button. Move any messages stored only on this Mac to On My Mac first.
2. Choose Mail > Add Account.
3. Select the provider from the table above.
4. Enter your account information. For Google, Microsoft, Yahoo and AOL you sign in on the provider's own page, so finish any two-factor prompt there.

Step 3: Gmail, Outlook.com and work accounts need the provider's sign-in page

Gmail and Outlook.com no longer accept a password typed straight into Mail. If either account was added as Other Mail Account with a user name and password, the server will keep refusing it, however correct the password is. The fix is to add it again with the Google or Microsoft Exchange option, which hands sign-in to the provider's own page.

Gmail and Google Workspace

Google's page on email clients is blunt about it: Gmail has stopped working with third-party apps that ask you to hand over your Google username and password. Google recommends the Sign in with Google option instead. Its own troubleshooting order for an app that can't sign in is: update the app, remove the Gmail account from it, then add it back with Sign in with Google. On a Mac, keeping macOS current covers the first part, since Mail updates with it.

App passwords are a fallback, not the fix. Google's app password page says they aren't recommended and are unnecessary in most cases, only exist when 2-Step Verification is on, and may not be offered at all if a workplace or school runs your account, if you use only security keys, or if you have Advanced Protection. Changing your Google password also revokes every app password you made.

For a Google Workspace address, one more thing can block you even with the right option: your organization's settings. Google's admin help says that if an admin turns IMAP off, people can't get their email in POP or IMAP apps, even if they could before. Admins can also limit IMAP to approved OAuth mail clients, with Apple Mac Mail on Google's list of examples. Google adds that since May 1, 2025, Workspace accounts no longer support less secure apps. If the Google option fails for a work address and webmail works, ask your IT team whether IMAP is on for your account.

Hotmail, Live and Outlook.com addresses

Microsoft switched off password-only (Basic) sign-in for Outlook.com accounts on September 16, 2024, according to Microsoft's notice for other email apps. An Outlook.com, Hotmail or Live account set up in Mail before then, or set up later as Other Mail Account, can fail with exactly this error. Delete it from Mail and set it up fresh, choosing Microsoft Exchange, which Apple says is the right option for these addresses on a Mac.

Work and school Microsoft 365 accounts

A work or school Microsoft 365 address also goes under Microsoft Exchange. If Microsoft's sign-in page accepts your password and Mail still can't verify the account, the block may be on your organization's side, since some companies limit which mail apps can connect. That's a question for IT, not a setting you can change on your Mac.

Step 4: Yahoo, AOL and iCloud: when you need an app password

An app password is a one-off password the provider generates for a single app, used in place of your normal one. Yahoo, AOL and Apple each require one in specific cases, and typing your regular password there is a classic cause of this error.

Yahoo and AOL

Choosing yahoo! or Aol. in Mail > Add Account uses the provider's own sign-in page, and in that case you sign in normally. An app password is only for apps that don't use that page, which in Mail means an account added as Other Mail Account. Yahoo's help page gives the steps:

1. Sign in to your Yahoo Account Security page.
2. Under External connections, click Create app password.
3. Type a name, such as Mac Mail, and click Generate password.
4. Enter that password in Mail's password field instead of your normal one, then click Done on Yahoo's page.

Yahoo suggests doing this in a browser you've used to sign in to Yahoo for several days, not a private window. AOL's help page describes the same process from its own Account Security page.

When I added my Yahoo address as Other Mail Account out of habit, my regular password failed every time. Removing it and choosing yahoo! instead took me to Yahoo's sign-in page, and I never needed an app password at all. That's the route I'd take first.

iCloud Mail

No app password is needed for iCloud if you turn iCloud Mail on through your Apple Account. Per Apple's iCloud guide, open System Settings, click your name (it heads the sidebar), click iCloud, then Mail (or iCloud Mail), and turn on Sync this Mac (on macOS Ventura 13 to 13.2, click Turn On). Your mail then appears under the iCloud heading in Mail's sidebar.

If iCloud Mail was added by hand as Other Mail Account, the rules change. Apple's iCloud server settings page says manual setup takes an app-specific password for both incoming and outgoing mail; your everyday Apple Account password won't be accepted there. Per Apple's app-specific password page, you need two-factor authentication on, you create one at account.apple.com under Sign-In and Security > App-Specific Passwords, and changing or resetting your Apple Account password revokes all of them. That last point can explain a sudden "unable to verify" error on an account that worked for months.

Step 5: Check the user name and server for other accounts

For a custom-domain, web host or work address added as Other Mail Account, this error often comes from the user name rather than the password. Some servers want your full address as the user name; others want only the part before the @, or a separate account ID your host gave you. iCloud is a good example: Apple's settings page says the incoming user name is usually just the part before the @, while the outgoing one is the full address.

You can see and change what Mail is sending in its account settings, per Apple's server settings guide:

1. Open Mail > Settings and go to the Accounts tab.
2. Pick the account in the list, then open Server Settings.
3. Under Incoming Mail Server, check User Name, Password and Host Name against your provider's published settings.
4. Do the same under Outgoing Mail Server (SMTP). The outgoing side has its own user name and password, and a stale one there makes sending fail even when receiving works.
5. Leave Automatically manage connection settings on unless your provider gives you a specific port and Authentication method. Turning it off reveals those fields.
6. Click Save.

For a work address on my own domain, I once typed my full email address as the user name when the host wanted only the part before the @. The password was right the whole time. Copying the user name format from the host's help page fixed it on the next try.

When the error appears on an account that used to work

If the account worked yesterday and today Mail says it can't verify the account name or password, something changed on the provider's side: usually a new password, a security check, or revoked app passwords. Apple's fix is to replace the saved password in Internet Accounts settings:

1. Quit Mail. If it won't quit, force it to quit.
2. Open System Settings from the Apple menu and click Internet Accounts in the sidebar.
3. Click your mail account, then click Details if you see it.
4. If there's a password field, delete the password and type the current one.
5. Close System Settings, open Mail and try the account again.

If the account has no password field there, it signs in through the provider's page, and the clean fix is to delete it from Mail and set it up again with the right option from Step 2. If Mail still won't verify it after that, Apple's last step is your provider: they can confirm your settings and that you're using the right password.

After a password reset, I update every Mac and phone that has the account the same day. A forgotten laptop in a drawer will keep trying the old password until someone updates it.

Quick checklist before you call your provider

• Webmail works with the same password, typed by hand.
• The account type matches the provider, using Apple's list (Microsoft Exchange for Outlook.com on a Mac, yahoo! for AT&T and migrated Comcast).
• Gmail and Outlook.com were added through their own sign-in pages, not as Other Mail Account.
• An app password is in place wherever the provider requires one, and was created after your last password change.
• The user name format matches what your provider publishes, on both the incoming and outgoing server.
• macOS is up to date, so Mail has current sign-in support.
• Your admin has allowed it for a work or school address.

If every box is ticked and the error stays, the account itself may be locked or suspended, and only your provider can tell you. For broader setup help, our Apple Mail guide walks through adding accounts from scratch, and Apple Mail vs. iCloud Mail explains which password belongs to which.
