  1. Go to your Google Account.

  2. Select Security from the sidebar.

  3. Under the How you sign in to Google section, select 2-Step Verification.

    • Choose Mail for Select app.
    • Choose Other for Select device, and enter a name for your Appsmith instance.

  6. Click the Generate button to create the app password.

  7. Copy the generated app password on the next screen, and keep it safe. You need it to configure Gmail on Appsmith in the next section.
