Password failed in Thunderbird

I have been using Thunderbird on a mac for years with no problems. Since yesterday, I have been getting login failed messages as my password is apparently incorrect. I am using macos 13.1, TB 102.6.1 and it is as a POP mail server. The error messages are attached. What is causing these failures? What login password is required? I have changed the password for this account everywhere I can find but these messages keep popping up every few minutes.

did you need to change your password with optus after they were recently hacked? Did you update it in Thunderbird?

I haven't changed my optus password for a long time., could the problem be that my optus account has been hacked?

I am not an optus customer, but they were hacked. It was huge in the news late last year. https://www.optus.com.au/about/media-centre/media-releases/2022/09/optus-notifies-customers-of-cyberattack

Normally following such an event customers are advised by the company involved to change their passwords just to be safe. I have no idea what Optus advised their customers. But I suggest you check with them.
