When you sign up for services on websites and in apps, you can let iPad create strong passwords for many of your accounts.
iPad on your iPad, tap All, then tap the account.
To later allow iPad to automatically fill in the password for you, tap Yes when you’re asked if you want to save the password.
Depending on the website or app, signing in with your saved password usually consists of steps similar to these.

Do one of the following:
Tap the account suggested at the bottom of the screen or near the top of the keyboard.
Tap > General > AutoFill & Passwords, then turn on or off AutoFill Passwords and Passkeys.
