What's Up With This Site's Login Procedure?

I’m using a password manager (LastPass) to log into On one computer there’s no problem logging in (I’m posting on this forum), but on another computer which uses the same password manager and the same browser (Edge), thinks I’ve got the wrong log-in details. So what’s up? I’ve already changed my password once thinking I must have made a mistake and I don’t want to change it again on one computer only to be told I’ve got the wrong log-in details on another.

Disappointing response to a problem that still persists.

This probably isn’t the forum for you to get help with your password manager
