Two-Factor Authentication (2FA) Challenge for Email-and-Password Users

Calendly uses Account Defender by reCAPTCHA to verify that the person logging in is the real account owner. To help keep your account secure, this tool may trigger a Two-Factor Authentication (2FA) challenge for email-and-password users.

How it works

  1. When prompted, you will receive an email from Calendly with a One-Time Password (OTP).
  2. Enter the OTP through the login flow to finish authenticating your account.

This added security measure helps to ensure that only you have access to your account. 

When are 2FA challenges triggered?

Calendly uses Account Defender by reCAPTCHA to improve security. This tool uses machine learning to detect suspicious logins by analyzing user activity.

If the tool detects a suspicious login, it will send a 2FA email to the user for extra security. This ensures only authorized users can access the account.

If you get a 2FA email, follow the steps to confirm your identity and secure your account. If you have any questions, contact our support team for help.

Where will I receive the 2FA email?

The 2FA email will be sent to your login email. If you don’t see it, check your inbox, spam, or junk folders for an email from Calendly.

Make sure your account email is current and checked regularly, as it’s how we’ll contact you about suspicious logins.

Having the correct email ensures you can quickly receive the 2FA email to confirm your identity and access your account.

For more information on managing your login preferences, see Calendly Account Settings.

Why am I not receiving the 2FA email?

If you're facing a challenge from Account Defender but not receiving the 2FA email, there could be a few reasons.

  • First, check that your account email is correct and that you have access to it. If you’re unsure which email is linked to your account, contact our support team for help.
  • You might have reached the limit for incorrect code attempts or new code requests. We set these limits to protect user accounts from unauthorized access.

If you think you’ve hit a limit or have questions about the 2FA process, contact our support team for help. We’re here to ensure your account stays secure and assist you in accessing it quickly.
