Hey! Co-founder of Infisical here. I'd say SSH certificate-based authentication is implemented widely at big tech and larger enterprises (tons of sources on it) but hasn't received the same mainstream adoption as SSH public key authentication because the administrative experience to set it up can be quite cumbersome despite how much benefit it provides. Put differently, there's always been a tradeoff in terms of configuration effort and benefits reaped. With Infisical SSH, we've tried to abstract away as much complexity as possible and give folks the ability to implement a SSH certificate-based access scheme across infrastructure with minimal administrative overhead.
