When is two factor authentication required?
There are a few situations where two factor authentication (2fa) is required, such as when logging into a financial account or accessing sensitive data. 2fa adds an extra layer of security by requiring two forms of identification, such as a password and a fingerprint.
In some cases, two factor authentication can be as simple as receiving a code via a phone call, or text message or email. However, some two factor authentication methods are more secure, such as flashcall. With flashcall, you receive a unique six-digit code that expires after 60 seconds. This code can only be used once, so it's important not to lose it or share it with anyone else.
If you're not sure whether two factor authentication is required, it's always best to check with the company or organization in question. They will be able to tell you what security measures are necessary. 2fa is an important way to keep your data safe, so make sure you're using it when needed.
