I can't even sign up with a password manager. Says the password is great (even has special chars) but then get an error saying it doesn't.

There was a problem with some special characters (they were not included in validation), and password manager would generate a password that is pretty good, but doesn’t have special characters I’ve initially chosen.

Now, I’m including most special characters, so it should work.

PS: Also, the pre-flight validation now includes special character check too, so you can see the validity real-time instead of after you submit. (This check was not originally included on the client-side, only on the server).

Why?
