@Edent While Apple dropped their prefix from the otpauth scheme, their approach is not “identical to Google’s.”
Apple:
issuer label prefix: “the proper name of your service”
issuer parameter: use a domain as “[Apple Passwords] uses this field to suggest credentials when setting up a new code generator”
Google:
“if both the issuer parameter and issuer label prefix are present, they should be equal”
(They conflict but my own tests show it is more pragmatic to follow Apple’s recommendations.)
@andrewe catch me up. What specifically are you referring to?
@Edent Your useful primer on the otpauth URI scheme and the lack of a formal specification: https://shkspr.mobi/blog/2022/05/why-is-there-no-formal-specification-for-otpauth-urls/
@andrewe Ahh! I see. That was written a few years ago. I've no idea what's changed in the meantime.
