How to Create a Google Workspace App Password for SMTP / IMAP?
Why Do You Need an App Password?
For apps or services that don’t support OAuth (such as some SMTP or IMAP email integrations), a Google Workspace app password is a secure way to grant access without using your main account credentials. It works only if 2‑Step Verification is enabled.
Step-by-Step Guide
1. Enable 2-Step Verification
Under "Signing in to Google", enable 2-Step Verification
Complete the steps (phone number or prompt required)
Wait 24–48 hours if "App Passwords" option doesn’t show
2. Generate App Password
Open this link: https://myaccount.google.com/apppasswords
Choose App: Other (Custom Name) → type “My App SMTP”
Click Generate
Copy the 16-character password shown, copy it now (you won’t be able to see it again).
3. Use in SenderWiz SMTP Settings
Use this app password in your SMTP setup:
SMTP Server: smtp.gmail.com
Port: 587 (TLS) or 465 (SSL)
Username: [email protected]
Password: [Your App Password]4. Revoke or Regenerate Later
Go back to App Passwords
Click “Remove” to delete and reissue if needed
✅ Summary Table
Enable 2‑Step Verification
Google Account → Security
Locate App Password option
Security page or search “App Passwords”
Create App Password
App Passwords → Other (Custom name)
Use in SenderWiz SMTP config
In place of your account password
Revoke unused passwords

🛠 Troubleshooting
If App Passwords is missing, ensure:
2‑Step Verification is active (not just 2SV enrollment)
“Skip Password When Possible” or policy-based settings aren’t blocking the feature.
Allow up to 2–3 days post setup for settings to propagate in Workspace Admin console—check back later.
