A one-time password (OTP) is an extra single-use password required in addition to your regular password to log into a computer or online service. The computer or service generates a one-time password for you on the fly to add an additional layer of authentication to help prevent unauthorized users from logging into other people’s accounts or stealing their credentials. OTPs are a first step in what’s called two-factor authentication. They’re becoming more common as cybercriminals purchase usernames and passwords online to commit ID theft.
