How are you using YubiKey? Is it worth $40 tag?

[faheemitian]

I didn't want to buy it because of the price tag, however, now since I have at least three good use-cases I feel like it's worth the cost. I intend to use it for GPG storage, GMail 2FA, and LastPass 2FA.

What are a few other good use-cases? How are you using it? Are there any cheaper alternatives?

Almost every other form of 2FA/MFA makes me nervous. I have three YubiKeys (one for my purse, one backup at home, and one unused). I only use them to secure various accounts.

Most people seem to have a backup one

Yes, I use it a lot. Gives me the freedom to carry my encryption keys (GPG) with me securely and I am able to use it on several systems.

Can you specify a few good use cases?

[sharjeelaziz]

I use it to store my GPG key and as a U2F key for my Google account.

logging in to github, google, your own PC, ... key to keepassxc saves multiple (x509) certificates

Great. Do Macs let you login with these? Let me google that.
