gmail-oauth2-tools VS go-samples

Shouldn't be _too_ hard to convert your scripts.

I ran into the same problem and one workspace disallows App passwords. You can simply get the OAuth token with a little python script and then use it as the password: https://github.com/google/gmail-oauth2-tools/blob/master/pyt...

(see for example https://github.com/lefcha/imapfilter/issues/186)

I tried to keep dependencies low, and while developing that and testing it I came across sendgmail. sendgmail is a little more polished but has a lot more dependencies, it's also not really setup to be imported into a project and used like a package.

Integrated with OAuth2 and register an app with Google to get a client secret. This should clear that up but honestly it's a hassle to do, I had a similar script (posted my story in another comment) and I always thought of going through and redoing it to authenticate with OAuth but it just seemed like a hassle. I found this which should help. https://github.com/google/gmail-oauth2-tools/wiki/OAuth2DotPyRunThrough

Fetch https://github.com/google/gmail-oauth2-tools/blob/e3229155a4037267ce40f1a3a681f53221aa4d8d/python/oauth2.py Store as ~/.mutt/oauth2.py Make it executable

I've seen mention of oauth2 for smtp being needed a couple times here so I finally took a look. I wanted to keep it dependency free so this only handles the smtp auth side of things. You will need a separate piece of software to handle the oauth2 token generation. I used this to generate my token.json and there's an example of using token.json to send an email in the smtpoauth2 repo.

You'll need to setup your oauth2 credentials.json and then use a tool like this to generate the token.json see sendmail in my repository for an example that loads token.json and sends an email.
