Generate App-Specific Passwords

App-specific passwords (also called app passwords) are required by most email providers when connecting third-party applications like Lumyvo via IMAP/SMTP.

What Are App Passwords?

App passwords are unique, randomly generated passwords that:

• Work only for specific applications (like Lumyvo)
• Don't expose your main email password to third parties
• Can be revoked individually without affecting your main account
• Provide enhanced security compared to using your regular password
• Bypass two-factor authentication for authorized apps

Why Are They Required?

Most email providers require app passwords to:

1. Protect your primary account credentials
2. Enable secure third-party access without compromising 2FA
3. Allow granular control over which apps can access your email
4. Comply with modern security standards

Important Security Note: Never use your regular email password with Lumyvo or any third-party app. Always generate an app-specific password.

Security Best Practices

Protect Your App Passwords

• Never share app passwords with anyone
• Store securely using a password manager (e.g., 1Password, Bitwarden, LastPass)
• Revoke unused passwords regularly from your account settings
• Use unique passwords for each application or service

When to Revoke App Passwords

Revoke an app password if:

• You're no longer using the connected service
• You suspect the password may have been compromised
• You're switching to a different email provider
• You're disconnecting Lumyvo from your email account

How to Revoke App Passwords

GMX: Account → Security → Two-Factor Authentication → Regenerate password Yahoo Mail: Account Security → Manage app passwords → Remove app IONOS: Email Settings → Security → App-Specific Passwords → Delete iCloud Mail: Apple ID → Security → App-Specific Passwords → Revoke Zoho Mail: Accounts → Security → App Passwords → Revoke

Troubleshooting

"Invalid credentials" Error

Possible Causes:

• Using your regular password instead of app password
• App password copied incorrectly (includes spaces or missing characters)
• Two-factor authentication not enabled on your account
• IMAP/POP access disabled in account settings

Solutions:

1. Verify you generated an app password (not using your regular password)
2. Copy the entire app password without spaces
3. Enable two-factor authentication in your account settings
4. Enable IMAP access in your email provider's settings
5. Regenerate the app password and try again

"Connection refused" or "Server not found"

Possible Causes:

• Incorrect IMAP/SMTP server address
• Wrong port number
• Firewall or network blocking the connection

Solutions:

1. Double-check the server settings for your provider (see tables above)
2. Verify SSL/TLS is enabled
3. Try alternative SMTP ports (465 vs 587)
4. Check your firewall or antivirus settings

App Password Not Generating

Possible Causes:

• Two-factor authentication not enabled
• Using free tier (Zoho Mail)
• Browser/cache issues

Solutions:

1. Enable 2FA on your email account first
2. Upgrade to a paid plan (for Zoho Mail free users)
3. Clear browser cache or try a different browser
4. Use a browser you've signed into recently (avoid Incognito)

Connection Works But Emails Not Processing

This is not a password issue. See the Connect IMAP/SMTP Accounts guide for troubleshooting email processing.
