The Security Center is where you manage everything that protects your MPChat account. Your security level is shown by five settings — Passkey, Login Password, Phone Number, Email and Google Authenticator; completing all five gives you the highest level.
Passkey: Add, reset or rename your Passkey. Since v1.5.0 the Passkey replaces the old payment password and verifies every sensitive action — applying for or deleting a card, sending red packets / transfers / internal moves, viewing card details, and freezing or unfreezing a card.
Login Password: Modify or reset your login password.
Phone Number: Change your linked phone number; the login phone number updates after the change. For security, withdrawals, transfers and red packets are disabled for 24 hours after the change.
Email: Change your linked email; the login email updates after the change.
Google Binding: Set up Google Authenticator to add two-factor protection to your MPChat account.
Lock Screen Protection: Once enabled, set a screen-lock password; the app auto-locks when running in the background. Choose the lock timing (every time, 1 min, 5 mins, 30 mins), Face ID unlock, and a Destruction Password (unlocking with it permanently erases all records — irreversible).
Account Cancellation: Your account data is permanently cleared after 7 days; logging back in during this period cancels the deletion.
More settings:
Two-factor authentication: phone / email / Google verification.
Device management: view logged-in / logged-out devices.
Lock screen protection: screen-lock password, lock timing, Face ID, destruction password.
Account deletion: deactivate your account (7-day cooling-off).
