OTPclient

Check to see if Hyperbola has that package or something similiar

edit:

its not there, but there might be others that are useful. Otherwise, you have to request it, i will update if i find one.

Although actually, I think one time password protection has limitations anyways... especially if it requires a phone number, etc...

As that would be easy for most people to crack.  Not that most people listen to this logic. 

most two account verifications aren't good unless you using a nitrokey based one. That's all I can think of literally...

Though Nitrokey is free hardware, I recommend asking them questions before you buy.

I am looking for something similar to the FreeOTP or AndOTP Android apps.

I already have them installed on my mobile but I would like to have something similar  available in my computer just in case that I eventually lose access to them through my mobile.

Thanks in advance for if you can give me some helpful advice with regard to this.
