Did you figure this out? I have the same issue. I have multiple envs, the pre-prod ones are obviously behind a firewall so I have: associatedDomains: [ 'webcredentials:.blabla.net?mode=developer', 'webcredentials:.blabla-test.com', 'webcredentials:*.blabla.com', ] It tells me: [Error: The operation couldn’t be completed. Unable to verify webcredentials association of <TEAM_ID>.<BUNDLE_ID> with domain <BUNDLE_ID>. Please try again in a few seconds.] Very unclear to me the association between bundle ID and actual domain names. The bundle ID does not match the domain names obviously. Find their documentation a bit unclear, which they had given real samples instead of XXXXX and YYYYY placeholders.

Same issue. Stopped working when my company changed to federated accounts (SSO). Tried generating a new app specific password but no luck
