[PM-32771] Passkey authentication fails with "Passkeys not supported for this app" error in X (Twitter)

[oakencore]

Origin

Native Application (non-browser app)

Web URL or App name

X

Passkey Action

• Creating new passkey (Registration)
• Signing in (Authentication)

Build Information

Version 2026.2.0 (21203)

Additional Information

When attempting to sign into the X (Twitter) Android app using a passkey stored in Bitwarden, the error "Passkeys not supported for this app" is displayed immediately after Bitwarden is prompted.

Steps to reproduce:

1. Have a passkey for X/Twitter saved in Bitwarden
2. Open X app → Sign in → Sign in with passkey
3. Bitwarden prompt appears, then shows "Passkeys not supported for this app"

The same passkey works on x.com in the browser.

X app version: 11.68.0

Issue Tracking Info

• I understand that work is tracked outside of Github. A PR will be linked to this issue should one be opened to address it, but Bitwarden doesn't use fields like "assigned", "milestone", or "project" to track progress.

I'm having this issue too. ProtonPass works perfectly.
