Associate Identity with Logins

Unfortunately, I don’t have a better way to do this.

The way I manage it is by adding a searchable string to the end of the account name for each detail an account has.
For instance “SomeAccount {B}{E}{P}”
I can search for {B} for accounts with birthday, {E} for email, {P} for phone etc.
If you wanted to include the detail itself, you could use {E:email@example.com} then find by searching {E.

Though this is far from ideal, so I’ve opened a FR Link Identities/PII and Cards to logins. Please vote on it if you want to increase chances of this feature being developed.
