Cannot log into email on iMac
I cannot access my email on my iMac. I recently changed my password for my ATT/Yahoo Email on my iPhone. I cannot access on my 2012 iMac; Catalina 10.15.7. I was able to log in to email on my iPad with the new password, but have been receiving error messages when I try on desktop. ("Failed to authenticate with Yahoo, please try again later"). Have been messaging with ATT but it appears to be an issue on my end.
iMac 21.5″, macOS 10.15
