Authenticate Users with One Time Passwords

One time passwords (OTP) sent over SMS are used to authenticate users attempting to access accounts, make purchases, or prove their identity. It is a highly effective security tool used as an integral part of multi-factor authentication for many use cases and  industries, such as the financial industry.

OTPs are typically a series of randomly generated numbers or characters sent directly to the user’s phone for a single login attempt.
