Check these in order:
- iOS AutoFill enabled? Follow FAQ #6 — SSO Vault must be ticked.
- Personal Credential Suggestions on? Open SSO Vault → Profile → Settings → toggle Personal Credential Suggestions ON.
- URL match? The URL on your saved credential must match the site you’re logging into. Edit the credential and make sure the domain is right (e.g.,
github.com, notlogin.github.com). - Try tapping the field again. iOS sometimes doesn’t offer AutoFill until you tap into the field a second time.
