# How to fix the issue where passkeys cannot be used in Firefox for Android

I encountered an issue where I could not use passkeys in Firefox for Android.

## Details of the issue

In Firefox Nightly for Android, passkeys had stopped working since about 1 to 2 months ago.

On Cloudflare's dashboard login page and in GitHub's two-factor authentication, where the fingerprint authentication screen for using a passkey should have appeared, nothing was displayed.

On these sites, passkeys were already registered, and when I used Chrome instead of Firefox, I could use passkeys without any issues.

My environment was as follows.

- Browser: Firefox Nightly for Android 150.0a1
- Device: Google Pixel 8
- OS: Android 16 Beta CP11.251209.009.A1

## Cause

When I investigated this issue, I found that [a report that the exact same issue was occurring on the exact same OS build](https://bugzilla.mozilla.org/show_bug.cgi?id=2009251) had been posted on Bugzilla.

According to this thread, updating to Android 17 Beta would resolve it.

In fact, after updating to Android 17 Beta CP21.260206.011, I was able to use passkeys without any problems.
