Just updated my gmail account. But how I update the new password in Mac email?

All of the above is not solving the issue that the gmail and gsuite accounts are simply not functional in the mail app if one never gets beyond the “authentication”- pop-up .... see screenshot. It does not open Safari or the page to enter a password or authenticate the mail access

This is the issue I posted about!

This is what I had to do (This is a workaround not a solution)

In google

1.) Turn off 2-step Verification

2.) Turn on Less secure app access

3.) In Gmail settings go to Forwarding and POP/IMAP and enable POP

In Apple Mail

1.) Add Account - use Other Mail Account fill with your credential - Sing in - it will get rejected

2.) change the incoming to POP

That should work just for mail, no calendar, notes or anything else

HTH

Open Keychain Access and search for your gmail account entry.

You can edit that or just delete it. If you delete it, Mail will ask for the password.

Try opening gmail in safari and log in.

Same here! Its a Safari 13 issue. Only Apple can fix it.
