Which method would be more appropriate in the form where a user enters a password such as a login form?

Note: Any forms involving sensitive information like passwords (such as login forms) should be served over HTTPS.

What is the best practice for password validation?

Adding numbers, symbols, upper and lowercase letters to the password makes it very difficult to brute force. Thus having a long, complex password is more secure. Try to make your passwords a minimum of 12 characters and spice them up with numbers, symbols, and mixed-case letters.

How do I secure autofill?

Go to Settings > System > Language and input > Autofill service. Note: Depending on your device model, the access to Autofill may be different from the above. Go to device settings and search for "autofill" or consult your device manual for more information. Select ID PROTECTION as your service, and then select OK.
