I have encountered this problem. Also, this password does not work when I try to login to a website again. My password is showing euro when I try again and again.
I don't know what the solution is but hive company I think it will be very useful for those who are new to me to understand if I manage it well.
I would use keychain instead of login. I haven't tried again since earlier, hope it gets back to normal, probably will.
I think users will have a lot of trouble using it if it doesn't return to normal
But I am hopeful that this problem will be solved soon. Everyone I have talked to has had the same problem because after this problem I contacted my friends and they saw the same problem and today I understood it through your question.
