how to change my mac mail password

Having the same issue. Somewhere (that I cannot find again) macOS/Mail pushed me to a browser to change my password. Ended up changing the wrong wrong. An hour later I finally got that one fixed. However the original problem has not...I have a gmail account for which I change the password via google, figuring I could update the Mac afterwards..but no, no way to do that.

Help!

Mac mail itself doesn't have a password other than the local PW you use to login to your Mac.

Each mail account (Yahoo, gmail, proton mail, Comcast and etc) each have their own password. What I do ... change it on the website and then make the commensurate change in Mac mail when told my current password is invalid.

I do that because I prefer to go directly to the source where the password is required and it precludes all the hunting and pecking for the password change facility locally..

Hi,

Following method could help your question.

Go to the Mail menu and select Preferences. Select Accounts, then type in your new password. On Outgoing Mail Server (SMTP) click on the drop down arrows. Click on the Advanced tab, then type in your new password.
