Have just bought a new iPad to replace 10 year old pad and have installed Bitwarden but cannot access my account . It says wrong password etc. I have checked, reinstalled etc is no go.
Keep trying - it is almost certain that you are entering something wrong, and it is not the device or a server-side problem.
There was some good advice in this recent thread:
Just some general ideas:
Are updates available?
Can you still log into the old pad? If yes, then compare the settings (time, timezone, date, keyboard layout, etc.) between both.
Are both devices connected to the same network?
