What is an App Password?
An "App Password" is a 16-character passcode generated by Google that allows a non-browser app (like SendScale) to access your account. This method bypasses the standard 2-Factor Authentication (2FA) prompt, allowing our servers to log in via IMAP/SMTP protocols.
When to use this:
You are using a legacy (free) @gmail.com account for testing.
Your organization strictly prohibits OAuth connections but allows IMAP.
You are experiencing persistent OAuth token revocations.
Phase 1: Google Security Configuration
Before you open SendScale, you must configure your Google account.
Log in to your Google Account and go to Manage your Google Account > Security.
Enable 2-Step Verification: This must be turned ON. Google will not allow App Passwords without 2FA enabled.
Generate Password:
Search for "App Passwords" in the search bar or find it under the 2-Step Verification section.
Select App: Choose "Mail".
Select Device: Choose "Other (Custom Name)" and name it "SendScale".
Click Generate.
Copy the Code: Google will display a 16-character code in a yellow bar (e.g., wxyz abcd efgh ijkl). Copy this immediately. You cannot see it again once you close the window.
Phase 2: Connecting in SendScale
Navigate to Accounts > Add New > Connect Your Existing Email.
Instead of clicking the big Google button, look for the text link or option for "Any Provider / IMAP / SMTP" (or use the Google option and look for "Manual Setup" if available).
Enter Credentials:
Email: Your full email address (e.g., [email protected]).
Password: Paste the 16-character App Password you generated in Phase 1. Do not use your regular login password.
IMAP/SMTP Settings (If prompted):
IMAP Host: imap.gmail.com | Port: 993 | SSL: Yes
SMTP Host: smtp.gmail.com | Port: 587 (TLS) or 465 (SSL)
Click Connect.
Verification
SendScale will attempt to send a "Test Email" to itself to verify the SMTP channel is open. If successful, the account will appear in your dashboard.
Pro Tip: If the connection fails immediately, check your Google "Forwarding and POP/IMAP" settings in Gmail to ensure "Enable IMAP" is toggled ON.
