If you use the term OTP (One-Time Password), it refers to a one-time password that is generated automatically, sent through SMS, and is valid only for starting a session or transaction. In general, it is highly recommended to check the number of mobiles, especially if your company allows online payments or manages user data that has some importance and confidentiality.
You may then wonder, “For what purposes is it used?” Well, these OTPs are quite useful and have started to be adopted by the entire industry for those services and systems that demand that the users’ identities be verified.
