iPhone keeps asking for email passwords on all of my accounts, outlook, hotmail etc.

I’ve seen on the thread that there’s been a large number of people complaining about having to re-enter email passwords over and over up to 6 times a day. This only started after the IOS 14 update and has been continuous since then 🤬 I’m fed up as effecting all my business emails as I don’t get messages and then find out it needs a password again and I’ve missed out on work as messages won’t deliver.

has anyone worked out a fix as apple don’t seem bothered?

Many thanks
