If you want to set Google SMTP to your application in Infix App then first you have to secure app or device permission to access your Google account. You need 2-Step Verification on your Google Account to follow the procedure.

An app password is a 16-digit passcode that gives a less secure app or device permission to access your Google Account. App passwords can only be used with accounts that have 2-Step Verification turned on.

Important: To create an app password, you need 2-Step Verification on your Google Account.

If you use 2-Step Verification and get a "password incorrect" error when you sign in, you can try to use an app password.

1. Go to your Google Account.

2. Select Security.

3. Under "Signing in to Google," select 2-Step Verification.

4. At the bottom of the page, select App passwords.

5. Enter a name that helps you remember where you’ll use the app password.

6. Select Generate.

7. To enter the app password, follow the instructions on your screen. The app password is the 16-character code that is generated on your device.

8. Select Done.

If you’ve set up 2-Step Verification but can’t find the option to add an app password, it might be because:

• Your Google Account has 2-Step Verification set up only for security keys.

• You’re logged into work, school, or another organization account.

• Your Google Account has Advanced Protection.

Tip: Usually, you’ll need to enter an app password once per app or device.
