i do not have anything important stored in secure folder. i disabled it once because every time i power up the phone, i get the secure folder notification and you need to unlock to remove it.That is not cool. Can you disable it in Settings?
I stand corrected on a previous statement. You can setup a PIN, password, pattern, or use fingerprint unlock. However, there is a toggle to reset using Samsung account.
Do you have anything important stored or installed (i.e. apps) in your Secure Folder that is not stored anywhere else?
Worst case scenario is that you will need to backup your data and factory reset your phone. That will reset Secure Folder back to factory default (and obviously delete anything in it). At that point, you should be able to enable it and set a new PIN or password. etc..i
just today, i wanted to reactivated it but it keeps asking for a password which i, sadly, i can't remember.
i had done factory reset a couple of times with my S22U, though i restored most, it still took time to get everything back to normal. so i do not think i would do a factory reset just to use secure folder.
for now, i keep trying different passwords and dealing with 'try again in xx minutes' when the password i enter is wrong.
