Updated 7 October 2026

Kaptcho uses Sign in with Viremail. There is no separate Kaptcho password.

How it works

  1. Open Kaptcho. On first open it asks you to sign in.
  2. Your browser opens on the Viremail sign-in page. Sign in as you normally do.
  3. Approve Kaptcho when asked.
  4. Switch back to Kaptcho. You are in.

Kaptcho never sees your password. It receives a private ID, your name, your photo and your email so it can show who is signed in and check your subscription.

No subscription yet?

If your account does not have a Kaptcho subscription, Kaptcho takes you to the Viremail Store. Once you have subscribed, open Kaptcho again.

Stuck on the browser step?

Check that your browser allows the page to hand back to the app. Then try signing in again from Kaptcho. If nothing helps, email [email protected].
