It's a great extension overall but lacks importing from other 2FA apps such as FreeOTP. This requires you to manually copy/paste or type your secret to the extension. It's okay if we have 2 or 3 services that we use 2FA to login but what if we have more? That's why I rate it one star less. However, gotta say it, this extension is still the best you can get and it's best at what it does.
