Every once in a while the system stops accepting my password.
Rebooting does not help.
Is it a regular interval? There are "expire password" options in the
user configuration, perhaps yours has been set.
I see that mine is set, but with a huge number before it's required.
The other thing to check is whether you have a bad key on your
keyboard, and that one of the letters you're typing isn't being
entered, or is double-entering.
If you have an international keyboard selected, perhaps some of the
keys aren't sending the characters you expect.

It seems the modern trend with Linux programmers is to change existing software
so that it's more annoying to use (e.g. making reboots required, when they
never used to be), then denying that *that* is a nuisance, then saying it's
necessary (ignoring that several years of prior versions didn't have that
stupid requirement), then complaining about being criticised for making things
worse. Don't try giving me an Emperor's New Clothes routine, it won't wash.
