Do security keys needed for Facebook expire? How long do they last? or Do security keys needed for Fa

"Hey guys, quick question – do security keys needed for facebook expire?

I’ve been using a Yubikey for my FB account, and it’s been working fine. But I just realized I’ve had it for like 3 years now??

Does FB make you replace these things after a while, or are they good forever? I don’t wanna wake up one day locked out because my key "expired" or something lol.

Also, if they *do* expire, how long do they usually last? Couldn’t find a clear answer in FB’s help stuff.

Thanks in advance!"
