I have set up the SMTP server, so I can send emails by using my Google Workspace Account and enabled App Password. Are there alternatives within the capabilities of a Google Workspace / Gmail Account, so I don't have to use this rather insecure method that grants access to my whole account?
TL;DR
Developers seeking alternatives to SMTP servers for sending emails using Google Workspace/Gmail accounts can explore using OAuth 2.0 authentication with Gmail APIs, which provides a more secure method without needing to share full account access.
