Trouble logging in?

I forgot my password

Enter your email above and tap Forgot password? We'll email you a link to choose a new one. It works for 2 hours (1 hour for affiliates).

I'm an affiliate and never made a password

Tap First time? Create your password on the Affiliate tab. We'll email you a link that opens your back office and lets you create it.

I saved my results before passwords existed

Your results are still there. Tap Forgot password? on the Member tab and we'll email you a link to create your password.

I didn't get the email

Give it a minute, then check spam or promotions. Make sure it's the same email you signed up with. Still nothing? Email hello@h2known.com.

It says too many tries

For your security, we pause logins for 15 minutes after several wrong passwords. Use Forgot password? to get back in right away.

I changed my email or lost access to it

Write to hello@h2known.com from your new address and we'll verify it's you and move your account.

My affiliate application is still pending

We review every application, usually within a few business days. You'll get an email as soon as you're approved.
