How do I get the macOS/iOS keychain to accept an all-numeric account name?
My Fidelity account uses my Social Security Number as an account name. I can't add a keychain item, however, that is only digits.
I first tried to add my account on my iPhone, but the "Done" button stayed disabled and I couldn't add the account. I canceled, tried again, and had the same result. Then I discovered by experiment that adding a letter to my account name (which made the name incorrect) activated the "Done" button.
So I saved that invalid account, hoping to fix it on my laptop using the Keychain Access app. But that app doesn't accept my edits, unless it's an edit which includes at least one alphabetic character in the account name.
How do I get my proper account name entered, which really, truly consists of only ASCII digits?
