Unable to Verify Account Name or Password on Mac

2019: Reported on MacOS Mojave (10.14.4)

Symptom: you get an error "unable to verify your email account name or password" from Mac Mail app.

Here is what you can try:

1- Fill in Email Password in System Preferences

The verifying problem may happen if you recently reset your Keychain's password.

If you cannot verify your account name or password in Mail app, try to type in the password to verify the account in System Preferences.

Here is how to do it:

• Open System Preferences and choose Internet Accounts.
• On the left panel, click on the account that you want to verify, then a pop-up will require the password.
• Press Cancel to view the detailed page of your email accounts.
• Type in password in the blank and press Tab button on the keyboard to move to the next field. (Tab not Enter).

2- Delete and Re-add Email Account

Deleting and re-adding the email account into the Mail app sometimes solved this issue.

Important: the email cache will be removed from the computer, but the attachments you've downloaded will not be deleted and the original data is still stored on the email server.

Method 1: Remove the email account from the Mail app

• Launch the Mail app.
• Click on Mail option at the upper menu, choose Preferences in the pull-down list.
• Choose the email account you want to delete on the left sidebar, and then click on the "-" button at the bottom.
• Click on "OK" to complete the deletion.

Method 2: Remove the email account from System Preference

• Open System Preferences and choose Internet Accounts.
• Click on the email account you want to remove, and then click the "-" button at the bottom.
• Choose "OK" to complete the deletion.
