If you forgot the login passcode:
If you forgot a passcode that you changed within the last 72 hours, see the "If you recently changed passcodes, use your old passcode to temporarily sign in" section of: If you see a iPhone, iPad, or Apple Vision Pro unavailable message or Security Lockout screen - Apple Support
Otherwise, see the other sections of that article
If neither of the above is an option, you will need to use a computer. See: If you forgot your iPhone passcode or your iPhone is disabled - Apple Support
or if you forgot the Apple Account/iCloud password:
There is an Apple article that explains what to do if you have forgotten your Apple Account password. Click on the following link: If you forgot your Apple Account password - Apple Support
