It's an arbitrary key value encoded in Base32, for example: `BVDRSBXQB2ZEL5HE`.

It contains an account name as a URI-encoded string. You can include prefixes to identify the provider or service managing the account. If you use prefixes, use a literal or url-encoded colon to separate the issuer prefix and the account name, for example: `GitHub:john-doe`.
