What two-factor authentication is and how it helps you protect your account

How two-factor authentication works

If you have this protection enabled, during sign-in, we will ask for:

• your username and password
• a one-time code that:

  • we send you in a text message or
  • you generate in the mobile app.

That way, even if someone steals the password for your Allegro account, they will not be able to sign in — because only you have the one-time code.

To make two-factor authentication more convenient, you can add your device to trusted devices. Then, you will not need to enter the code every time you sign in. Check how to use this option.

How to enable two-factor authentication

You will enable two-factor authentication in the tab with the same name. The process will look different, depending on how you want to receive the one-time codes.

1. Open the Two-Factor Authentication tab and click [Let us begin].
2. Select text messages as the way to receive the codes and click [next].
3. Enter the phone number to which you want us to send codes. If that phone number is already assigned to your account — you can select it from the list or enter a new one.
4. Next, click [send code].
5. Enter the code from the text message you receive.
6. Click [enable]. Done!

How to enable two-factor authentication with a code generating app

6. For security reasons, provide a phone number to which you want to receive a text message with the code when you cannot access the app. If that phone number is already assigned to your account — you can select it from the list or enter a new one.
7. Next, click [send code].
8. Enter the code from the text message you receive. Done!

What a trusted device is

If you are the only user of the device with which you often sign in to Allegro, you can add it to trusted devices — a list of devices you have chosen, where we do not ask for a one-time code during sign-in.

This means we will only require a code when you use an unknown device or when someone tries to hack into your account. On a daily basis, you will sign in quickly and conveniently.

How to add a trusted device

You can do it in the Two-Factor Authentication tab or while signing in on that device.

How to add a trusted device in the Two-Factor Authentication tab

1. Open the Two-Factor Authentication tab on the device you want to add to trusted devices.
2. Click [add to trusted] in the Trusted devices section.

How to add a trusted device during sign-in

1. Open the sign-in page on the device you want to add to trusted devices.
2. Enter your username and password. Click [sign in].
3. Enter the code from the text message or app.
4. Select the Do not ask for a code on this device option.
5. Click [confirm code].

How to change the phone number used for two-factor authentication

1. Open the Two-Factor Authentication tab.
2. In the Text message section, click [change settings].
3. Click [change phone number].
4. Provide the new phone number and click [send code].
5. Enter the code you received on the new number.
