Mojave 10.14.4 update causes mail passwords not to work After 10.14.4 my hotmail and ntlworld mail accounts will not login. Have checked passwords and theses are the same ones that still work on the iPad and iPhone . But re-entering on iMac says "unable to verify account name or password".
The question "mail for mac will not accept my password" has an answer about "app-specific passwords" and talks about 2-level authentication .
What should I do ?
Do I have to make new passwords for hotmail and ntlworld?
Or is there a bug fix coming?
Help!!!!
I assume you are using Apple Mail to collect your mail?

One solution that seems to work for many is to delete these accounts entirely then go to Sys Prefs > Internet Accounts and re-establish/enter them.  That's why I did and it worked just fine for me (and for others).
