# Log In to Your impact.com Account
Learn how to log in to your impact.com account in different scenarios and how to log in securely using two-factor authentication.
#### Login scenarios
How you log in to your impact.com account depends on how you originally signed up. For more information see our [Log In to impact.com FAQ](/other/readme/log-in-to-impactcom-faq.md).
You signed up via email
If you signed up with a single email address, and not via SSO, then you can log in with your email address, or your username and password.
You signed up via SSO
If you signed up using one of the SSO options provided, select it when logging in and follow the prompts.
* Alternatively, you can enter your email address which will prompt you to log in via the SSO option you signed up with.
You signed up for multiple accounts via the same email address
If you signed up for more than one account using a single email address, then you won’t be able to log in using your email address, and must log in with your username and password.
#### Log in with Two-Factor authentication
You can log in to your impact.com account securely by using two-factor authentication (2FA). You'll first have to enable 2FA in your security settings.
You'll be prompted to verify your identity via 1 of 3 methods, depending on which 2FA method you enabled for your account. If you enabled multiple verification methods, you can bypass the default method by selecting **Verify with other options**.
{% tabs %}
{% tab title="Authenticator app" %}
When logging in with this method, you will see the following:
1. Open the authenticator app you used [when setting up 2FA](/other/readme/enable-user-level-two-factor-authentication.md) for your account.
* The app will generate a Time-based One-Time Password \[TOTP] for you.
2. Enter the TOTP as your verification code.
3. Optionally, select  **\[Unchecked box]** **Save this device** if you don’t want to authenticate future logins from the device you're using.
4. Select **Verify**.
{% endtab %}
{% tab title="Text message" %}
When logging in with this method, you will see the following:
1. Check the mobile number you used [when setting up 2FA](/other/readme/enable-user-level-two-factor-authentication.md) for your account.
* You will receive a text message via SMS with a unique verification code.
2. Enter the verification code.
3. Optionally, select  **\[Unchecked box]** **Save this device** if you don’t want to authenticate future logins from the device you're using.
4. Select **Verify**.
{% endtab %}
{% tab title="Email" %}
When logging in with this method, you will see the following:
1. Check the email address you used [when setting up 2FA](/other/readme/enable-user-level-two-factor-authentication.md) for your account.
* You will receive an email with your unique verification code.
2. **Enter** the verification code.
3. Optionally, select  **\[Unchecked box]** **Save this device** if you don’t want to authenticate future logins from the device you are using.
4. Select **Verify**.
{% endtab %}
{% endtabs %}
{% hint style="info" %}
**Note:** Each verification code is valid for 10 minutes, and any code received during this window can be used. If your code doesn't arrive immediately, please wait for the 30-second timer to expire before trying again.
{% endhint %}
