Keycloak get user password - keycloak

Question

In my project, I need to get current user password from Rest API.
I searched keycloak 4.8.3 final documentation but I could not find it. With admin user I can change password without knowing the current password. But my logged in user can be admin or not. I found that keycloak does not give me permission to that because of security. Wrap up is there any way to active that settings or is there a way to get password with Rest API ?
Thank you.

Update: The /auth path was removed starting with Keycloak 17 Quarkus distribution. So you might need to remove the /auth from the endpoint calls presented on this answer.
Via the Rest API, one cannot get the password for obvious reasons. Ideally, in a secure setting, even if one is the admin one should not have access to the users' passwords.
From the comments you wrote:
I could use method like boolean isPasswordCorrect(username,password)
An approach is to create a client on your Realm as follows:
Go to your Realm;
Clients;
Create Client;
Set Access Type to public;
Set Direct Access Grants Enabled to ON;
Save;
Now request from the newly created client a token on behalf of the user that you want to check if the password is correct:
As you can see the endpoint is:
<KEYCLOAK_HOST>/auth/realms/<REALM_NAME/protocol/openid-connect/token
and the body is:
client_id : <The client ID of the newly create client>
username : <The username>
password : <The password to be tested>
grant_type : password
If the password is correct you will get back a token object, otherwise you will get the following response:
{
"error": "invalid_grant",
"error_description": "Invalid user credentials"
}
