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

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 team,

            I've implemented passkey (webauthn). All browsers working fine along with firefox for regular passkey But we implemented ROR (well-known/webauthn) for cross domain using rpid (https://web.dev/articles/webauthn-related-origin-requests). Only this is failing for cross domain passkey in firefox where other browsers working good. I am using firefox version 140.14.0. I know its bit old but just asking does it support? We've some limitation so not able to test latest version of firefox. I am getting below error in console

"A resource is blocked by OpaqueResponseBlocking."

Any help regarding this will be appreciated.

Regards! Sourav

Hi, the problem is simple: I cannot pass the security gate of Facebook/Meta at passkey scan. Just because Firefox engine doesn't fire the passkey options from Windows Security.

May the dev team see this before I switch to Chrome as my default browser, as this has been inconvenient for months. And you won't happen to see this bug.

To the community, if you know how to fix it, would love to get your advice.

Thanks, T.

Hello,

I am trying to set up firefox to add a passkey to sign in into bitwarden.

In bitwarden I added my Yubico key in order sign in into my account. Unfortunately, when I try to log back into my account with my Yubico key it doesn't work.

Does firefox support passkey ?

Thank you very much in advance for any help.

I want to use passkeys while also using Firefox. I read an online article that says this function is considered to be experimental. If so, it seems that it is experimental only with Firefox. I'm able to use them on every other browser I have. Where is the Firefox version that supports them?

I can't log on my Amazon account because I keep getting a request for a passkey setup from Firefox with a USB. This goes beyond my tech savvy. I was working fine before. This started with my last order with Amazon a couple of weeks ago. Can this situation be resolved from my Mozilla account and how?

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!

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

In recent months, Firefox has begun to nag me to assign security keys to various sites. I don't need to do this because I have excellent protection from LastPass. How can I turn this nagging thing off?

I'm trying to sync my DuckDuck Go (DDG) search engine and Firefox data to a new pc. I haven't used or reset my Firefox password since (it looks like) 2014. When I tried to change my password, it required me to enter my old password, which if I knew it... So, I tried "forgot password" and it asks me for my many symbol/digit passkey - also which I don't know. But I'm in all my accounts on phone, tablet, and pc running Ws 10. But I need to switch full time to Ws 11. Please help.

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.
