Answer 1

After looking for a while, I found it can help

I looked for where the message came fromץץ and i found that this message "Invalid credentials." coming from this path.

vendor\symfony\symfony\src\Symfony\Component\Security\Core\Resources\translations\security.en.xlf

so i copeid the file security.en.xlf into app\Resources\translations and made some change to the part i wanted to translate

<trans-unit id="4">
    <source>Invalid credentials.</source>
    <target>Username/password doesn't match</target>
</trans-unit>

Btw, in my case, I just uncomment the following line in config.yml :

framework:
    translator: { fallbacks: ['%locale%'] }

And my locale was set to "fr"

parameters:
    locale: fr
