How do I authenticate my mobile number?
Phone-based authentication involves sending a one-time password (OTP) to a user over a separate communication channel (e.g. SMS, MMS, WhatsApp, Facebook Messenger, Viber or even voice) from the IP channel (internet) used by the application, providing security in case the IP channel is compromised.
How does phone authentication work?
Phone authentication allows users to sign in to Firebase using their phone as the authenticator. An SMS message is sent to the user (using the provided phone number) containing a unique code. Once the code has been authorized, the user is able to sign into Firebase.
Is phone number authentication secure?
With all of these SMS attacks and security issues in mind, it's clear that hackers are growing more sophisticated every day; even small amounts of information can be used to hijack mobile phones, spoof user identities, and access accounts. So, to answer the question: no, SMS authentication is not entirely secure.
