For security reasons, customers who do not have two-factor authentication (2FA) enabled are required to enter a one-time authentication code when logging in from an unfamiliar location. This one-time authentication code sent via email helps to keep your account secure.

Please check your email for a message from do-not-reply@poloniex.com containing this code. If you do not see it in your inbox or spam folder, consider adding this email address to your contacts and trying to login again.

This code is only valid for 5 minutes and will fail if your IP address changes during the process. If you attempt to login after the code is expired, you will receive a new email with a new code and will have to try again.

We strongly encourage you to enable 2FA to make your account as secure as possible. You can do this in your profile settings and the 'Two-Factor Authentication' section.

If you are logging in from a new IP with two-factor authentication (2FA) enabled, a one-time authentication code will be sent to your email to keep your account secure.

Please check your email associated with your Poloniex account for an email named “Log in from New IP” from do-not-reply@poloniex.com, click on the URL link to confirm, and follow the steps to log in again with the new one-time code.

The confirmation link has a time limit, so if the link does not work please try to login again.
