Firebase Sign in with Phone Number implements several measures to prevent the misuse of disposable phone number services:
Requiring a minimum age: Firebase Sign in with Phone Number requires users to be at least 13 years old to use the service, which helps to prevent minors from accessing disposable phone number services.
Phone verification: Firebase Sign in with Phone Number verifies the user's phone number through a code sent via SMS or voice message. This process ensures that the phone number belongs to a real user and not a disposable phone number.
SMS rate-limiting: Firebase Sign in with Phone Number limits the number of SMS verification requests that can be sent to a phone number within a certain time frame. This prevents automated scripts from spamming the service with requests.
IP address blocking: Firebase Sign in with Phone Number blocks IP addresses that are suspected of malicious activity or attempts to use disposable phone numbers.
Requiring a unique phone number: Firebase Sign in with Phone Number only allows one account per phone number, which prevents the creation of multiple accounts with the same disposable phone number.
Overall, Firebase Sign in with Phone Number's combination of phone verification, rate-limiting, IP blocking, and unique phone number requirements makes it difficult for users to misuse disposable phone number services.
