We have no problem providing links to older versions of SCLogin that, hopefully, will work without issue. However, we won't be able to provide any support for older versions.
Obviously, we'd recommend you upgrade to the latest version of Joomla for the best compatibility and security features. It's usually a 1-click process, but I'm sure you know this and have your reasons for not wanting too.. but, as a developer.. I have to say it
Unfortunately, the furthest back our system goes is to SCLogin v8.4.7 from earlier this year. The major release before that (8.3) was on an older distribution system and not something we have access to anymore.
SCLogin v8.4.7 - Released May 27, 2021 - This was before all of our work for Joomla 4, so should be further backward compatible than the current v9 release:

Hopefully, that works for you.
Good luck,

Edit: Original link was incorrect and to v9. Fixed.
