bug: Does not work with QR Code from HCL Notes

[simsonntag]

Bug type

Error at runtime

App version

Version: 5.4.9

Device environment

Galaxy A55 5G, Android 14

Bug description

While trying to scan an 2FA-QR-Code created by HCL Notes the App shows "This QR Code does not work."

It is easily scannable with Google Authenticator and the secret was working after typing it down manually.

Maybe the software uses some parameter, that cannot be pasted by 2FAs.
This is the structure of the shown QR Code:

otpauth://totp/ISSUER%3A%22USER%22%20USER%40Domain.de?secret=PRDMZQT5I5FCFKD3KEV6RXA5MOJESJ4GEKMK9MZQXQ2EPK7WP4DGOF7TL5KNY2FEQNNV3SWIPPXTPISKSQKWDSZ3YXQ5UK2UT2S44LQ&issuer=ISSUER&algorithm=SHA1&digits=6&period=0

I guess it may be the period=0, which brings the problem.
Other apps may switch to a default value of 30 in such a case.
