That GSuite setting **affects all IMAP security modes** (Unsecure, Implicit and Explicit) when using the `Authenticate` method.
We use **IMAP over TLS/SSL to connect to Gmail** which is the secure way to access your Gmail account. Here are some workarounds for this issue:
- Use **OAuth 2.0** to connect to Gmail. We will update this post with a blog post on how to connect to Gmail using OAuth2
- Use **Application specific passwords**
- Turn on 'less secure apps' option.
The Google support page for this issue does not make much sense on what 'less secure' really mean. There are many mail clients that use IMAP TLS/SSL to connect to Gmail. Are they all 'less secure'?
It looks like Google want to limit places that store your GSuite passwords.
