See my comment symfony/symfony#54881 (comment): We should document how we can leverage AutowireCallable to gain access to the password strength computation in arbitrary services.

For the documentation, do we update the validator documentation? I've not seen a dedicated PasswordStrength constraint documentation

And for the autowiring so we update the generic container documentation or do we add it linked to the constraint/validator doc?

I was looking on my phone, now that's it's cloned, I found the PasswordStrength doc file.

As there is no dedicated documentation for the Validator itself and only for the constraint, I would proposeto add a section "Learn more" at the end of the PasswordStrength constraint doc page that would link to a new page:

• How to get or override the estimated strength computation

The new page would simply indicate :

1. that the method estimateStrength in the Validator is now public (+ providing a link to the lines in the code)
2. if that method is not aligned with the needs, there is a way to udpate the estimation method for the Validator using a dedicated closure as argument of the Validator and refer to the following page of the container doc : https://symfony.com/doc/current/service_container/service_closures.html

Would that be a good fit? I'm willing to take a shot at this but it will be my first time updating the documentation, so I might need some guidance (reading the contributing guidelines is ongoing).

Sounds good to me. Feel free to submit a first draft and we iterate from there.

Closing as fixed in #19910.
