Passkeys not supported on Galaxy S23 Ultra?

EeCw — Mon, 27 Oct 2025 16:09:11 GMT

I have Passkeys set up on mySamsung Galaxy S23 Ultra.

Trying to secure my account in the EE app.

I go through the steps and then get this below. :

"Your device doesn't support passkeys

We couldn't create a passkey on your device.

Hi @EeCw

Odd as I have this set up on my S24 Ultra.

Are you using the default firmware. Have you checked your app is up-to-date.

Thanks

Hi,

Thanks for your reply confirming this should work.

I have the latest Samsung firmware and Android version. I have even uninstalled the EE app then reinstalled but still the same problem.

I have a Passkey working on my Samsung already for another app.

Any suggestions most welcome, EE?

Thanks again

Hi @EeCw,

Thanks for visiting the EE Community

Which is the default browser you use on your phone? I had the same message on my S24+ when I set mine up, my default browser was Duckduckgo, but I switched it back to Samsung Internet for the passkey setup and was able to without getting the error message.

So worth trying an alternative browser to complete setup with to see if that is the issue.

Hi Alex,

Thank you, this has sorted it. I did try this before but with my Nordvpn on too so perhaps the site protection or whatever is broken.

I couldn't even log in to post this reply without changing to Samsung browser. I've reported broken site to DDG.

Cheers for your help!
