When you say this, I presume you have 2FA enabled for your Bitwarden login (As is HIGHLY recommended 
)
Were you not being prompted for 2FA when entering your login information correctly as you said?
When able to successfully login with those credentials you were then prompted to authenticate with your 2nd factor authentication method as expected in the multiple browsers?
One thing I would double check when entering the Master Password, you can toggle the visibility of your password by clicking the “eye” icon next to the password field, which should look like this → 👁
This way you can be sure the proper information expected to be entered is working to login, and there are not any incidental spaces or other characters.
