Firefox Community Forum

The following content is machine translated: The passkey feature (login via QR code scanning with a mobile phone) is not available the Linux version of Firefox. Compared to Windows and macOS, the Linux version does not have a passkey option when logging in; it only has a "security key."(as shown in the image) I cannot use the pass key saved on my iPhone to log in to websites, which is very frustrating. Is this a bug or an incomplete feature? Thank you for your reply. device: archlinux

Untranslated (chinese) : 通行密钥功能（通过手机扫描二维码登录）在linux版的firefox上并不能使用，相比windows和macos，linux版在登录时并没有通行密钥选项，只有一个“安全密钥”（如图），我无法使用保存在iPhone上的通行密钥来登录网站，这很令人沮丧，这是一个bug还是没有完成的功能？感谢您的回复 设备：archlinux

THis is such nonesense. I have no idea what the hell happened with creating a passkey. Of course the damed thing disappeared the moment I took the next step. I HAVE NO IDEA OF WHERE I AM IN THIS LUDICROUS PROCESS. It started with going to Google Docs where I am writing a novel and being told I had signed out of Synchronisation. Clicking on it produced this madness. HELP!

I was creating two-factor authentication for my account and when I tried to create a passkey the only options were to use iPhone, iPad, or Android device, or Security key (see screenshot).

There's no option to add the passkey to a password manager (I'm using BitWarden).

I'm using Firefox Version 155.0 (64-bit) on Windows 11 (25H2).

Hello,

I am trying to further secure my Mozilla account and was delighted to see that they added support for passkeys. I am signed into my Proton Pass on Firefox addon, but Firefox does not seem to understand it is supposed to create the passkey inside Proton.

This is unlike behavior I have witnessed on other sites supporting passkeys which has worked flawlessly to set up, such as Amazon.

Mozilla passkey will not download to thumb drive. Am I missing something when attempting to set up a passkey through USB connection? Using Windows 10 on a laptop. Regards, George

Everyday Shopify asks me to verify my account but when I try to do so using my passkey it fails with the following error message: “We’ve encountered an error accessing your passkey. Try again or use a different method.”

When I hit the “Verify” button I can see a POST request being made to https://accounts.shopify.com/user-verification/passkey?native_app=false&os_name=other&token=XXXXXXXXXX and it gets a 200 response with the following JSON:

``` {

 "result": "error",
 "reason": "user_submission_canceled_passkey",
 "credential_options": {
   "challenge": "YYYYYYYYYYY",
   "timeout": 120000,
   "extensions": {},
   "allowCredentials": [
     {
       "type": "public-key",
       "id": "ZZZZZZZZZZZZZZ"
     }
   ],
   "rpId": "accounts.shopify.com",
   "userVerification": "preferred"
 },
 "selected_method": "passkey",
 "other_info": {},
 "severity": null

} ```

(I’ve redacted some information from the request URL and the response body)

The passkey popup from Bitwarden never opens.

I then use 2FA with my authenticator app and am able to login.

I’m using Firefox 153.0.1 and the Bitwarden extension 2026.7.0.

This used to work fine for me some time ago and I can still use passkeys using Chrome + Bitwarden on the same computer.

I've contacted Bitwarden's support and they tell me the problem resides either with Firefox or with Shopify. I've also posted this issue in Shopify's community forums and people tell me it looks like it's Firefox who's cancelling Shopify's POST request given the "user_submission_canceled_passkey" error code.

I couldn't save my key because the tab closed automatically during a computer bug. (to the "fbi agent in my computer": fu.) I'm guessing that it was an issue with my computer and not the browser, but in case it is a firefox issue:

firefox opened two of my browser extensions that were in the extensions folder:

• Adblock, with a page highly pushing to give them money
• Capital One Shopping, with two identical user agreements I was meant to sign

I don't need a detective on the case, but I would really like to get my encrypted key somehow. and if it didn't give the fbi agent more sensiti!e info, that would be great.

Thanks!

When I try to log in to EE, I am asked for my passkey. I don't have one, presumably it is on a thumb drive but none of mine offer the solution. Neither do I remember setting one up. Seeking further information I am told it is required by Firefox. I have searched Settings but no joy. Can you help?

Thank you, Robin Brookes
