I would like to password protect my device, but I'm afraid to hit enable if I don't know if there is already a password. I know some phones come with a pre-assigned password. If I hit enable and I have never assigned a password, will it ask me for one?
I sure done't want to lock my phone and loose all my information.
No, it wont ask you for one. But it will ask you to create one, and if you forget it you'll only get ten times to try and put it in correctly before it automatically wipes your phone.
When you disable the password (if ever), it'll ask you for the password.
Then, when you re-enable the password, you have the opportunity at that time to use the old password or enter a new one.
