Pay Ops - short document required - list of login options and how each of them works

Trish would like a short document that compiles what login options are available, and which internal or external users use each of them. This can be pulled from existing docs and public website

idir, bcsc and bceid/2fa and identity affidavit

Start by reviewing the existing documentation and public website for the listed login options: IDIR, BCSC, BCEID/2FA, and identity affidavit. Done means a short document explains how each option works and identifies which internal or external users use it.
