Voice over Internet Protocol (VoIP) numbers are increasingly popular for communication due to their flexibility and accessibility. However, when it comes to two-factor authentication (2FA) or verification systems, VoIP numbers may face limitations or restrictions.
Two-factor authentication is a security process that requires users to provide two different authentication factors before gaining access to an account or service. These factors usually include something the user knows (like a password) and something the user possesses (like a mobile phone).
Using VoIP numbers with 2FA
One of the limitations of using VoIP numbers for 2FA is that they might not always be recognized or accepted by all platforms or services. Some websites, apps, or services prefer to use traditional mobile phone numbers for authentication purposes due to concerns about the reliability and security of VoIP services.
Users may encounter difficulties when attempting to use VoIP numbers for 2FA, as not all services or systems accept them as valid authentication sources.
Using 2FA with Aircall SMS
While some Two-Factor Authentication services that use SMS to send a token or message may work with Aircall SMS, we can not guarantee this for a variety of reasons, and do not recommend or support the use of these services with Aircall SMS.
We recommend exploring alternative authentication methods supported by your service provider for optimal security and functionality.
Please consult your service provider's guidelines and best practices for authentication to ensure compliance and optimal performance.
