Migrate OTP/Notification/Messaging from Telegram to Signal with Configurable Channel
Menu path: Log in
PMS now sends the login OTP and its system notifications through Signal instead of Telegram. The login OTP arrives on Signal by default. If it does not arrive, you can pick another channel (Telegram or Email) on the login screen and request the code again. Booking, FnB, housekeeping and task notifications go to the hotel’s Signal groups. A system administrator can enable, disable or switch the channel between Telegram and Signal in the system configuration.
Before you start
- Install the Signal app and register it with an active phone number.
- The same phone number must be saved in PMS, with the country code: +84 for Vietnam, +855 for Cambodia.
- The email address that receives the login OTP must be correct in PMS. If it is wrong, you cannot get the OTP by Email.
