# Login and logout

## **Log in to** Spark

1. Access Spark with the provided login URL. Most links to Spark should be constructed as `https://spark.{environment}.coherent.global/{tenant}`. A tenant is a separated part of the computing environment allocated to one client.
2. If your organization has enabled Single Sign-On (SSO) you will see another button below *Log in*. Click that button to enter Spark.
3. Otherwise, enter your Email and Password. This account should be assigned either by the Spark tenant administrator from your organization or provided by the Coherent team.
4. To save the login details for future logins, check the box next to *Remember me*.
5. Click **Log In**.
6. The browser will navigate to the [Home](/navigation/home.md) page.

If Single Sign-On (SSO) has been enabled for your tenant, there may be another button under **Log In**. Clicking that button should automatically continue the login process.
{% endhint %}

## **Log out of** Spark

1. Click the user menu (the top right corner) on the header navigation and click Logout.
2. Spark will give a warning message that confirms the logout action.

## **Reset password**

1. If the password has been forgotten or the password reset email has expired, visit the login URL and click *Forgot password*.
2. Follow the steps to receive a verification code to the registered email address to create a new password.

If the *Forgot password* was not received, please check the following:

1. Please check the correct email address was used as the user name.
2. Check the Spam / Junk / Custom mail folders.
3. Add `no.reply@coherent.global` to any email allowlists.
4. Request another password link from the login page by clicking *Forgot Password*.
