Security researchers at Mysk also found this same info was sent in analytics, which may be linked to your email address and phone number. Similarly to Duo Mobile, Authy’s backups don’t encrypt some information that you might expect it to, sometimes including the name of the website and a username (you can edit these, but we suspect few people bother to do so). But for most people, the potential security risk of backing up codes online is outweighed by the fear of being locked out of accounts for good, so for the apps that do offer backups, we looked for clear explanations of how the backups worked, where they’re stored, and how they’re encrypted. So we looked for authenticators that left this feature opt-in. Optional backups: The security researchers we spoke with said they don’t recommend backing up or syncing a two-factor authentication account because then your tokens are on the company’s servers, which could be compromised.Going with a reliable company helps guarantee continued support for new mobile operating systems and tech support if something goes wrong.

Reliability: Pretty much anyone with an app developer license can make an authentication app, so when it came to security, we looked for apps that are open source or run by well-known companies like Google, Twilio, Cisco, or Microsoft.

The FBI does warn people about the risks of SIM swapping and phishing tools, but two-factor authentication is still effective in protecting accounts. Not much data is available about the specifics of phishing attempts like this, but the FBI’s Internet Crime Complaint Center received 25,344 reports of phishing in 2017 (PDF).

Unlike a stolen password, two-factor authentication software tokens need to be grabbed in real time to be useful. Someone could email you a link to a fake Gmail login page saying your account needs an update, where you then log in with your username, password, and two-factor authentication token. It is still susceptible to advanced phishing attempts. But two-factor authentication isn’t perfect-no security tool is.

Two-factor authentication can protect against more-basic phishing attempts, such as when a fake login page tries to steal your password.
