How can I change the password on an Android phone?

To change the password on an Android phone, open the Settings app and go to Security, Lock Screen, or Passwords & Security depending on your device brand. Tap Screen Lock and enter your current password or PIN. Then choose a new lock method such as a PIN, password, or pattern. Create your new password and confirm it to save the changes. Using a strong password with numbers, letters, and symbols can improve phone security and help protect your personal data from unauthorized access.
