How to Fill Email Password vs App Password in AtomEmailPro (Very Clear Guide)

When adding an account in AtomEmailPro, many users get confused:

👉 Which password should go into which field?

This guide will explain it in the simplest way possible, based on how you actually use the software.

🔑 The Most Important Rule (Read This First)

In AtomEmailPro, it depends on how you send emails:

✅ If you use web login (browser sending):

👉 Fill your email password into the Email Password field


✅ If you use SMTP sending:

👉 Fill your App Password (or email password) into the App Password field

1. What is “Web Login Sending”?

This means:

  • The software opens a browser
  • Logs into your email (like a human)
  • Sends emails from the web interface

👉 Just like you manually log into Gmail / Outlook / Yahoo

✔ What to fill:

  • Email Password field → your normal email password

2. What is “SMTP Sending”?

This means:

  • The software sends emails through SMTP server
  • No browser login involved

👉 This is a technical sending method

✔ What to fill:

  • App Password field →
    • App Password (if required), OR
    • Your normal email password (for some email types)

3. Examples (Very Easy to Understand)

✅ Gmail

  • Web login sending →
    Email Password = your Gmail password
  • SMTP sending →
    App Password = must generate in Google

✅ Outlook / Hotmail

  • Web login sending →
    Email Password = your password
  • SMTP sending →
    • No 2FA → use normal password
    • With 2FA → use App Password

✅ Yahoo Mail

  • Web login sending →
    Email Password = your password
  • SMTP sending →
    App Password = must generate

✅ Domain Email (Company Email)

  • Web login → may not be supported
  • SMTP sending →

👉 App Password = same as your email password

4. Common Mistake

❌ Filling everything into the wrong field

Example:

  • Using SMTP but putting password in “Email Password”
  • Or using web login but not filling Email Password

👉 Result: login fail or sending fail

5. Final Simple Memory Trick

Just remember this:

👉 Web login → use Email Password field
👉 SMTP sending → use App Password field

That’s it. No need to overthink.
