You need to get rid of Master Password completely:
- Tell RoboForm not to password-protect new Passcards and Identities.
- If you have already created a number of password-protected Passcards and/or Identities, you can remove password protection from them by going to RoboForm -> Options -> Security, clicking "Set Master Password, Mass Protect/Unprotect", checking the "Remove Master Password" option and clicking OK.
- If you forgot your Master Password then click "I forgot it!" button in the Set/Remove Master Password dialog.
