T-Mobile partners with AT&T and Verizon to launch ZenKey mobile authentication service


Usually when we’re talking about T-Mobile, AT&T, and Verizon in the same sentence, it’s because T-Mo is poking fun at its rival US carriers. This time, though, the three companies are working together on a joint venture.

T-Mobile, AT&T, and Verizon have rolled out a new mobile security solution for consumers. Called ZenKey, it’s meant to make it easier for you to log in to apps and websites, letting you just tap a button rather than having to remember and manually enter multiple passwords.

ZenKey uses a multi-factor authentication method to protect you and keep identity thieves from getting your logins and info. Because ZenKey is made by the US carriers, authentication uses several details that you’d use with your wireless network, including your phone number, SIM card details, phone account type, user credentials, and account tenure.

Once you’ve downloaded the ZenKey app, you can set it up with your info and secure it with a fingerprint or face scan. And after you’ve begun logging into apps using ZenKey, you can use this main app to manage the info that your carrier shares with other apps, like your name, phone number, and mailing address.

Apps that support ZenKey will have a “Sign in with ZenKey” button that allows you to log in with one tap rather than entering a username and password.

You can find the ZenKey Powered by T-Mobile app right here. It’s available to T-Mo customers on postpaid, prepaid, and business plans. Metro by T-Mobile customers can’t currently use it.


The prospect of having a one-tap login using a service like ZenKey that protects your credentials and means you don’t have to keep track of multiple passwords and usernames is attractive. However, this means you also have to hope that all of the apps you use adopt this login method, and ZenKey is only supported by a handful of websites and apps to start. Those include the LiveXLive and Verizon My Fios apps and the websites for AT&T TV, DirecTV, myAT&T, AT&T TV Now, and “Currently, from AT&T.”

    So sites are going to need to add a “Sign in with ZenKey” button for us to use it… I wonder how well that’ll get adopted.

    Also, not that long ago, all three of these carriers were giving away our detailed location history to anyone who gave them $100… Do we really want to trust them with our log in info?

    Sure, they probably won’t offer our login tokens for sale… But I’m sure they’d still happily accept the $100 in exchange for telling future employers, abusive partners etc what accounts 555-555-5555 has in their ZenKey locker.. Or maybe telling a “researcher” who has an account at embearsing-kinky-fetish(dot)com and a few days later you get a “Get me 2,000 bitcoin or else everyone knows your a freak!” text…

      I think people who own crypto get fished a lot more often than people who do not, and ppl and companies whose data are time sensitive and life or death are more prone to ransom attacks

    I don’t know why they would advertise something that gets a solid 1 star in the play store! How stupid is that?

    Apple already has one login built into iOS and secure and its Not Zenkey

    I’ll just keep using my 2FA app and password vault. For now I’ll have any easier time logging into things since it works with everything. There would have to be some over the top advantage to use ZenKey and the carriers would have to prove it. Then I’d still only consider it – not fully adopt it.

    Google and Apple already do this. This sounds like it’ll be a little more secure but it’s worthless when it requires an app/site to support it in the first place.
