I forgot my phone password at first (I don't know how I forgot it, I think the phone didn't recognize the passcode because I use the same code on all my devices and I'm 90 percent sure it's correct)

Then I retrieved the iCloud password after waiting 7 days to format the phone

I formatted the phone and re-entered the iCloud account on the phone and reset the passcode for the phone, but I can't access full encryption unless I enter the old passcode

I tried several attempts with the old code until it started asking to delete the iCloud data

I want to access the saved passwords
