No. WipeAway never sees, receives, or stores your Google password under any circumstances.
WipeAway uses Google's official OAuth 2.0 authentication system — the same standard used by millions of apps that integrate with Google services.
Here is exactly what happens when you sign in:
At no point in this process does WipeAway receive, handle, or store your password. Google keeps your password entirely to itself.
The token Google provides to WipeAway only grants permission for the two scopes you approved: calendar access and reading your email address. It cannot be used to access Gmail, Drive, or any other Google service. It also cannot be used to change your Google account password or security settings.
You can revoke WipeAway's access token at any time via your Google account settings. See How do I revoke WipeAway's access?
