"Incorrect password" message when it is ABSOLUTELY the correct password

I created an account to use on my Linux machines. From the start I have had nothing but issues. The very first password I setup and immediately had the browser save wouldn't work an hour later. Still signed in on the original machine I had setup the account on but got an incorrect password error when attempting to login on another machine. I know the password was correct. Regardless I changed the password thinking it might fix the problem. It didn't. I just got signed out of the first machine. After some fighting I got a password to work and was able to get signed in on all 3 machines. Attempting to sign in on a fourth machine I get the incorrect password error. Go to my account from one of the machines that is currently signed in and verify it is the correct password. Decided to change password again to see if that works as it did previously. You have to enter the old password to set a new one. It says the password is incorrect. I was able to login on my phone using the Google account login option. Please help.
