microsoft & gmail continually forcing password change, what is workaround?

have an annoyance that I i'd like to know a workaround for please:
-often/frequently/ nearly everytime i use MS 365 sign in or gmail sign in it takes me to a password reset. i have no wish to change my password { also previously did but it still kept wanting me to do so immediately after!]

how can i stop this please.
