Hello, I have an iPhone, I forgot a password, and I remember the previous codes. Can you help me?

If your phone is locked after too many wrong attempts, the only way back in is to reset, even if you remember your passcode.

If you forgot the passcode on your iPhone, or your iPhone is disabled or unavailable -

If you see an iPhone or iPad unavailable message or Security Lockout screen - Apple Support

Sorry, but knowing your previous codes won't help you. As Kurtosis12 has already mentioned, the only means to regain access to your iPhone will require you to restore it. That process will completely erase your phone, and you will need to restore from a backup if you need to access your data.

There is nothing anyone here, nor Apple can do to help you with this.
