Flash calls are a great option for 2FA!
There are a few reasons why flash calls are a better choice than SMS when it comes to user authentication. For one, flash calls do not require a data connection, so they can be used even in areas with poor or no cellular coverage. Additionally, flash calls are less likely to be intercepted or blocked by carriers than SMS messages, making them more secure. Finally, flash calls can be made directly to the user's phone number, so there is no need to worry about storing sensitive information in a third-party system.
Flash calls are a great option for 2fa because they are more secure and less likely to be intercepted. If you're looking for a cheap and easy way to add an extra layer of security to your online accounts, flash calls are the way to go!
