Hey, thanks you for the up to date info, i have some problems with login and database authentication, can u make a video expaining it?

[@joseluizdurigon8893]

What if i want to persist the password and username (basically all the User data) in the database and retrieve from it?

There seems to be a problem with authentication when an account exists but the wrong password is entered. Does anyone have a solution?

[@thangbui-hd5le]

I fixed by add one line of code "authenticationManagerBuilder.parentAuthenticationManager(null);" to authenticationManager method in SecurityConfig class. This is modified code: @Bean
public AuthenticationManager authenticationManager(HttpSecurity http) throws Exception {
AuthenticationManagerBuilder authenticationManagerBuilder = http.getSharedObject(AuthenticationManagerBuilder.class);
authenticationManagerBuilder.parentAuthenticationManager(null);
authenticationManagerBuilder.userDetailsService(userDetailsService()).passwordEncoder(passwordEncoder());
return authenticationManagerBuilder.build();
}

When you have a username but the password is incorrect it goes into an infinite loop of database queries, does anyone know how to fix it?

[@thangbui-hd5le]

I fixed it by add this one line of code "authenticationManagerBuilder.parentAuthenticationManager(null);" to authenticationManager method in SecurityConfig class.
