Two-factor authentication on LinkedIn

LinkedIn publishes software of its own for this and also takes an open authenticator code. What choosing either one commits you to, and what happens when the phone holding those codes is gone.

What LinkedIn supports

These are the second factors LinkedIn offers on linkedin.com. Which ones you see can depend on your plan and your country; what each of the seven actually costs you is set out once.

MethodWhat it is
Authenticator app (TOTP)SupportedComputed on your own device; nothing is sent to produce it.
The service’s own appSupportedSoftware this service publishes; it works, and only here.
SMS text messageSupportedTexted to your number, so your carrier is part of the lock.
Hardware security keyNot offeredA physical key you tap; the one option phishing does not beat.

What that particular mix means

LinkedIn offers both SMS and an authenticator app. They are not equivalent — a texted code depends on your mobile carrier and survives no longer than control of your phone number, while a generated code never travels. If both are enabled, the account is only as strong as the weaker one, because an attacker picks.

LinkedIn also publishes its own app for this — LinkedIn App. It works, and it works only here: an account secured that way needs that software on whatever device you are holding.

Where this page's facts come from

Of the fifty services on this site, nine publish software of their own as a second factor, and LinkedIn is one of them. Two of the fifty accept exactly this combination, so the same decision comes up on one other service here. Among the eight services filed under social, three accept a hardware security key — LinkedIn not among them.

The directory files LinkedIn under social, records three of the seven second factors it tracks, and points at instructions published at www.linkedin.com/help/linkedin/answer/544.

Switching on an authenticator app

LinkedIn's own instructions: LinkedIn — two-factor authentication — linked, never copied, because a stale menu path here locks people out.

If the phone holding your LinkedIn codes is gone

LinkedIn publishes no dedicated page for losing your second factor, which in practice means the route back is ordinary account recovery: proving who you are to support, on their timetable.
