3 months ago Hi, The QR code contains a string formatted according to the otpauth uri format. One of the format rules is:
The issuer prefix and account name should be separated by a literal or url-encoded colon, and optional spaces may precede the account name. Neither issuer nor account name may themselves contain a colon
Last time this issue was reported (see #234) it shows that Microsoft uses this colon to identify the company name when the 2FA protects a professional account:
Microsoft:CompanyName:Firstname.Lastname@company.comMicrosoft does not respect the otpauth format, it's why it's rejected by 2FAuth.
Here is a workaround:
- Decode your QR code here: https://joohansson.github.io/offline-qr/src/qr-reader.html (This page will decode the QR code without sending any data on the network)
- Copy the Result string
- Open 2FAuth, click the New button, then Import
- Paste the string into the Direct Input textarea
- Before submitting the string, replace the colon that separate the company name from your account id with any string
- Click Submit
Version
5.2.0
Details & Steps to reproduce
When importing Microsoft entries (always starting with Microsoft:) from Google Authenticator on Android via live scan function the entries show up with the error message "LABEL MUST NOT CONTAIN A COLON.=" and can not be imported.
Expectation
A colon in the label not breaking the import.
