Brief Summary

According to the otpauth uri format spec the label must not contain a colon, either raw or url encoded. When generating an otpauth uri, keepassxc uses the url encoded entry label as otpauth label, which causes at least some authenticators / parsers to fail parsing.

Steps to Reproduce

1. Create as password entry containing a colon in its label (for example a website url include http://)
2. add TOTP settings
3. get otpauth uri via QR code or secret service integration

Expected Versus Actual Behavior

Colons should probably be sanitized from the label to produce a working uri
