Hello I recently foundmy iPhone 8 and I forgot the password to it so I tried a couple different ones I know
eventually it locked me out saying iPhone unavailable but I now remember the password.
I have my phone in recovery mode connected to my computer but it's still asking for the password but I cannot place it into the phone because iPhone says unavailable.
iPhone 8 Plus
You'll need to reset the iPhone. See:
If you forgot your iPhone passcode, use your Mac or PC to reset it - Apple Support
If you still can't restore it, then you probably set Activation Lock on it. You might be able to remove the Activation Lock through iCloud:
How to remove Activation Lock - Apple Support
If that all still fails, you'll need to contact Apple Support for further assistance. Be prepared to provide proof that this is your iPhone, such as with the original receipt showing the serial number of the iPhone.
Good luck.
Forgotten password got locked out then I remember again but can’t get in
