Hello Kayou,

you first need to create some OTPs in the account section of the application.
Once you have created them, print them out and keep them in a safe
place (possibly inside your wallet) with no reference to Clipperz
and/or your actual username on the sheet.

Once you have done this, when you need to use an OTP to login from an
untrusted computer, you just need to fill the login form with you
usual username, click the "use a one-time passphrase" check, and fill
the 4 fields that will replace the passphrase field with the
components of one of the OTP you have created earlier.

That's it.

The OTP you have used will be disabled, so next time you will need to
use a different one.
You can create as many OTP as you want.

Hope this helps.

Regards,

Giulio Cesare

That reminds me of something I've been wondering since I first started
using Clipperz; why are the one-time passwords four separate fields?
Why not just one big field like the regular password?

Hello Adam,

we have opted for the 4 separated fields for a couple of reasons:
- make it visually different from the passphrase field, so that you
would not miss which you were actually using;
- create a loose connection between the OTP (spelled in 4 major blocks
separated with hyphens; and each major block split in half with a
simple space, just to make it all more readable);
- having to type 4 eight random characters blocks instead of one
single block of 32 random characters seemed more reasonable. Remember
that you will rarely have the option to cut/paste an OTP; most of the
time you will have to transcribe something you have written on a piece
of paper.

There are probably other useful trade-offs, but we thought that the
current arrangement made sense.

I hope you agree with me. :)

Regards,

Giulio Cesare

Ah, that all sounds reasonable. Thanks for the explanation :)

Thank you Giulio

It's clear for me now and very smart for safe use in public places.
Thank you also for your reactivity
