Logging into Pulsar is the same as logging into Salesforce mobile, because Pulsar uses the same SDK. For this reason, Pulsar does not require a separate login and uses your Salesforce login.
If you have never logged in as a user, just launch Pulsar and it will present you with the login screen with an option to login to Production as a default choice. You can always choose a different connection type to login to Sandbox or a Custom/Community URL. The screenshots below will walk you through that process.
If you are already logged in as a user, you must get back to the login screen to login as a different user.
Launch Pulsar.
If you are already logged in and on the Home screen:
a. Click the settings button (gear icon) in the lower right corner of the screen.
b. Click the Switch/add user button.
3. Click Select another account.
4. Choose an account email and click Select or Click New User, if the account is not in the list.
