Security Sysadmin Google Authenticator

Also an added bonus if GA is linked to your phone number with iMessage...you can also receive authentication codes via Messages app on OS X

 

Thats the issue with GA. I had issues when I got a new phone and wiped the old one after forgetting about GA. Took a while to regain access to my accounts. Authy handles this alot better.

 

Theres always this

GitHub - authy/authy-ssh: Easy two-factor authentication for ssh servers

but they charge you up to $0.09 per auth after 100 auths per month.

 

Found this
Use One-Time Passwords for Two-Factor Authentication with SSH on CentOS 7

but in my opinion unless you have national secrets on your server it seems overkill

 

I think it's stable , been using it for a few months now with no issues whatsoever on my end

 

You're right, but most people including myself are either too lazy or couldn't be bothered to save the security key or backup codes. Google just needs to add a transfer phones or backup option.

 

You have 5 emergency codes. Its good even if you loose your phone.

 

nice what repo has google-authenticator in it for centos 7, can't seem to install it, i already have epel and remi

 

ya if that't the case i'll hold off on installing it then, i wanted an easy way to remove it if things go sideways

 

I like this one also
