“Failed to read credential from QR code”

[Socob]

• Yubico Authenticator version: 5.0.2
• Operating system and version: Ubuntu 19.10
• YubiKey model and version: YubiKey 5 NFC
• Bug description summary: Yubico Authenticator does not recognize QR codes generated by a specific site (error message: “Failed to read credential from QR code”).

Steps to reproduce

1. Open Yubico Authenticator with the YubiKey inserted.
2. Open the attached QR code on the screen:
3. Click the “Add a new account button”.
4. Click “Scan”.

Expected result

Yubico Authenticator should parse the QR code as normal and add the new TOTP account to the YubiKey.

Actual results

Yubico Authenticator displays the message “Failed to read credential from QR code”.

Other info

QR codes generated by other sites work for me, it’s just this specific one. The otpauth:// URI seems fine to me, so I’m not sure what the issue is?

(Note: There is no sensitive information in the QR code.)

Same error message here with at least Atlassian and DocuSign affected. The Yubico playground and Facebook ones worked fine though. In my case:

• Yubico Authenticator version: 5.0.3
• Operating system and version: macOS 10.15.4
• YubiKey model and version: YubiKey 5C

Same issue here attempting to scan a Office 365 QR code at https://mysignins.microsoft.com/security-info

It does not work for me, but a colleagues YubiKey 5 does work on Windows 10 20H2

My details;

• Yubico Authenticator version: 5.0.5
• Operating system and version: macOS 11.5 and Windows 10 Home 20H2
• YubiKey model and version: YubiKey 5

Yubico Authenticator 6.0 has now been released and uses a new codebase. As such, this issue has been marked with the legacy label, and will be automatically closed in 7 days. If this issue is still relevant to Yubico Authenticator 6, please comment on the issue saying so, and it will be kept open (or be re-opened). Sorry for the inconvenience!

For me Yubico Authenticator works correctly since several months. A remaining problem is sometimes, that the QR codes contain a too long "Issuer" name. Then "Add account" button becomes inactive. The solution is to shorten the "Issuer" name manually (maximum 26 characters).
