One Time Password (OTP)

What is One Time Password (OTP)?

OTP is an acronym for One Time Password. It is also sometimes referred to as a One Time Passcode, or a One Time PIN.

OTP is a password or code that is valid for only one login session or transaction, on a computer system or other digital device.

A OTP is typically sent to a user via either SMS to a mobile phone or to the user's email address, and are frequently used as part of two-factor authentication (2FA).

All MIDAS room booking systems support optional 2FA in the form of a 6-digit OTP sent to the user's email address upon each login attempt.
