Signing in with a one-time code

How sign-in works without a password, and what to do if the code does not arrive.

Radar has no passwords. Instead, we email you a short one-time code each time you sign in. It is safer than a password, and there is nothing to forget.

How to sign in

  1. Go to the sign-in page and enter your email.
  2. Open the email from Radar Lab and copy the code.
  3. Type the code into the sign-in page. You are signed in.

You stay signed in on that browser for a while, so you will not need a code every time.

If the code does not arrive

  • Wait a minute. Emails can take a little time.
  • Check spam and Promotions folders.
  • Check the email address for typos.
  • Ask for a new code. Only the newest code works, so use the latest email.

Common questions

I paid for Pro with a different email. Can I still sign in?
Yes. Sign in with your usual email, then message us. We will move your plan to the email you sign in with.
Can I change my sign-in email?
Message us and we will change it for you.
Is it safe that there is no password?
Yes. Only someone with access to your email inbox can get the code, and each code works only once.
