If you have stumbled upon the issue where you are unable to verify account name or password on Mac then you are not alone in this. Many other Mac users are encountering the same issue. The good news, however, is that addressing this issue can be done by applying a few simple troubleshooting methods. So, have a look at what this issue is all about, and how to fix it.

What it is all about?

If you are unable to verify your email account name or password from the stock Mail app on Mac while the same account or password has been verified successfully on other devices then you need to solve this issue. This issue has been a center of attention for quite a few years, but it keeps coming back from time to time. Users are complaining that there is no permanent fix to that, but in reality, there are a few things that you can do to put this to bed once for all. Here is what you can do about it.

Fill in Email Password in System Preferences:

If you have just recently reset your Keychain’s password then this could lead to this verifying issue. If you are unable to verify the account or password then you can try to type in the password to verify the account in System Preferences. Here is what you need to do.

1. Launch the System Preferences on your Mac.

2. Choose the option Internet Accounts.

3. You will be able to see the accounts that can be verified on the left panel. Choose the account that you want to verify by clicking on it.

4. Doing this will prompt a pop-up asking you to key in the password. Choose the option cancel and it will allow you to view the detailed page of your email accounts.

5. Key in the password in the blank space and then hit the tab key. The system will now verify the account given that you have provided the right password.

6. You can repeat the same process to verify different accounts.

Delete and Re-add the Email Account:

Another solution to fix this issue is to remove the email account from the Mail app only to add it again. This may sound like an unlikely trick for fixing the issue, but it has worked for many users. Remember, removing any email account will also remove its cache along with it. However, the attachments you have downloaded via this account will remain unharmed and the original data will still remain stored on the server. Have a look at the method that can help you in deleting the account.

1. Open the Mail app.

2. Click on Mail option at the upper menu, and choose Preferences in the pull-down list.

3. Click the – icon next to the account you want to delete and then click OK to complete the deletion.

4. Alternatively, you can head to System Preferences and choose the option Internet Accounts. Repeat the aforementioned step to delete the account.

5. Once the account is deleted, reboot your Mac and then add the email from scratch.

Deactivate Two-Steps Verification Security:

Most renowned service providers such as Gmail, AOL, and Yahoo include a Two-Step Verification to add an extra layer of security. No denying that it ensures utmost security, but at the same time, t’s a double-edged sword as this means vulnerable email apps cannot verify the account and password.

The best way to go about this is to temporarily shut down the two-step verification. Now try verifying the account on the Mac and it will be successful. Once the account is verified, enable the two-steps verification back. All this makes for an excellent, win-win situation, isn’t it?

Delete Offline Mail Cache Folder:

What if the issue is solely down to you being careless and lazy about your device or account? For instance, if your Mailbox is taking more time to open then it is an indication that you should do some cleaning. Clearing the offline cache is important; it is more important if you facing trouble in verifying the accounts. Many users have reported that clearing the cache didn’t only speed-up their system, but it also eliminated this unwanted verification error. Here is what you need to do.

1. Run Terminal Window, type in the following command “defaults write com.apple.finder AppleShowAllFiles TRUE;killall Finder” and hit Enter to view the hidden cache files.

2. Now shut down the Mail App.

3. Open the cache folder by following the route mentioned below.

4. Users > your_profile > Library > Mail > IMAP_account_name.

5. Now simply remove the folder .Offline Cache.

6. The new cache folder will form automatically when you launch the Mail app next time.
