How to set up an SMTP G-Suite account to allow full Google authorization
Check the following settings while setting up a G-Suite account via SMTP to avoid connectivity issues by allowing full Google authorization:
Setting 1. Whitelist Snov.io with OAuth ID
To protect your data more thoroughly, Google has provided a requirement of whitelisting applications. It is required that your G-Suite Administrator adds our application as a whitelisted application to avoid an “Unverified Application” prompt when authorizing.
Here’s how to whitelist Snov.io:
In order to perform the following steps, сheck if you signed in as a super administrator.
Step 1. From the Admin console Home page, go to Security.
Step 2. Click API Permissions.
Step 3. Add Snov.io to Trusted Apps. At the bottom of the list of apps, click the Trusted Apps link.
Step 4. Click the “+” icon (Whitelist an App) in the bottom right corner.
Step 5. In the Select App Type list, select option Web applications.
Step 6. Specify the Snov.io OAuth2 Client ID:
Step 7. Click Add.
For more information, consult the Google documentation on how to manage access to third-party apps with new G Suite security controls.
Setting 2. Set up 2-Step Authentication
2-step authentication adds an extra security layer to your email account and prevents unauthorized access to it.
In your Google Account, in the Sign in & Security section choose Signing in to Google. Click on 2-Step Verification. Select Get started.
Set up your phone number and choose the way you want to receive your security codes. Confirm that it works and turn the 2-step verification On.
Setting 3. Add an App password
An App password is a 16-digit passkey that gives an app permission to access your Google Account. If you use 2-Step-Verification and see a “password incorrect” error while trying to access your Google Account, an App password may solve the issue.
In your Google Account, select Signing in to Google. Click on App password. Choose Other (Custom name), insert Snov.io and generate the app password.
Save the generated app password and use it when setting up your SMTP sender account instead of the password to your account for SMTP credentials.
Setting 4. Enforce less secure apps
Access to less secure apps will be set for everyone and users won’t be able to turn off access to less secure apps. Use this option only when you want to ensure that access by a less secure app is available to all users.
Note that Google doesn’t recommend this option, as it potentially increases the risk of hijacking user accounts.
- Sign in as a super administrator.
- In the Security section choose Basic settings.
- Under Less secure apps, select Go to settings for less secure apps.
- In the subwindow, choose the Enforce access to less secure apps for all users.
