== What is 2FA? ==
{{seealso|Two-factor authentication}}
2FA, or ''two-factor authentication'' is a way of adding additional security on your account. The first "factor" is your usual password that is standard for any account, the second is a code retrieved from an external device such as a smartphone, or a program on your computer. It is conceptually similar to a keycode device you may have to use when logging into [[internet banking]].
The technical name for this is "[[Time-based One-time Password Algorithm]]", but as its acronym is the same as a [[TOTP|popular music show]] featuring [[Jimmy Savile]], we won't be using that here. == Why on earth do I need this? ==
