Recovering from a forgotten password
If you did not lock your phone and you forget your password, you can
delete the password from your phone. Deleting a forgotten password also
deletes all entries and files marked as Private.
Important: If you synchronize with your computer before deleting a
forgotten password, your phone restores your private entries the next time
you perform a HotSync operation, but it does not restore the password.
To delete a forgotten password:
1. Tap the Password box.
2. Tap Lost Password .
3. Hold Option and press Return for Yes.
