Starting a CI 4 project: best auth library?

I'm starting a CI4 project in about 1 month.

I'm choosing my Auth library:

1) Ion Auth https://github.com/benedmunds/CodeIgnite...uth/tree/4
Last update is about 1 year ago. Is it still valid?

2) Myth Auth https://github.com/lonnieezell/myth-auth
It seems really good but they says it doesn't work with 4.0.3 
So is it useless right now for me? I'll release my project in about 2-3 months.

3) Any other library that you use?

Thank you
Alberto
