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

Calendly utilizes Account Defender by reCAPTCHA to ensure someone logging into an account is the actual owner. To help keep your account secure, this tool may trigger a Two-Factor Authentication (2FA) challenge for email-and-password users.

Here's 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 will help ensure that only you have access to your account. 

When are 2FA challenges triggered?

At Calendly, we use Account Defender, a tool by reCAPTCHA, to enhance security for our users. Account Defender uses machine learning to identify suspicious logins by analyzing user activity within our app.

When the tool identifies a potentially suspicious login, a 2FA email will be triggered to the user for an extra layer of protection. This helps ensure that only authorized users have access to their account.

If you receive a 2FA email, please follow the instructions provided to confirm your identity and secure your account. If you have any concerns or questions, please reach out to our support team for assistance.

Where will I receive the 2FA email?

The 2FA email will be sent to the email address associated with your account login. If you are expecting a 2FA email but have not received it, please check your inbox, as well as your spam or junk mail folders, for an email from Calendly.

It is important to ensure that the account email address is up-to-date and regularly monitored, as it will be the primary means of communication in the event of a suspicious login.

If you have changed your email address since creating your account, or if you are unsure which email address is associated with your account, please contact our support team for assistance in updating your information.

By receiving the 2FA email at the correct email address, you can quickly and securely confirm your identity and access your account.

Why am I not receiving the 2FA email?

If you are receiving a challenge from Account Defender but are not receiving the 2FA email, it could be due to a few different factors.

  • It’s important to check the email address associated with your account to make sure it is correct and that you have access to it. If you are unsure which email address is associated with your account, please contact our support team for assistance.
  • It’s possible that you have hit a limit on the number of incorrect code attempts or new code requests. In order to maintain the security of our users’ accounts, we have implemented limits on the number of attempts or requests to prevent malicious actors from accessing someone else’s account.

If you believe you have hit a limit, or if you have any other questions or concerns about the 2FA process, please contact our support team for assistance. We are here to help ensure the security of your account and assist you in accessing it as quickly and easily as possible.
