Earlier this year, Netlify decided to deprecate [Netlify Identity](https://www.netlify.com/changelog/deprecation-netlify-identi...), which was a huge blow to Decap CMS users. There was no longer a go-to auth solution for simple DecapCMS use cases.
This pushed me to develop a full-featured solution for the Decap CMS community: DecapBridge
In short, it lets anyone with a Decap CMS website quickly setup auth in a way that anyone with an email address can safely access the CMS and collaborate on content. No need to create a github / gitlab account.
Users can also use Login with google or Login with Microsoft (more to come) to login and edit the content.
As a site admin, you also get an administration interface to invite / kick out users easily.
Let me know if you try it out!
