By a simple google search you can find a lot of samples and documents for your question, as springs docs says you can use in memory authentication as below:

@Bean
public UserDetailsService users() {
    UserDetails user = User.builder()
        .username("user")
        .password("{bcrypt}$2a$10$GRLdNijSQMUvl/au9ofL.eDwmoohzzS7.rmNSJZ.0FxO/BTk76klW")
        .roles("USER")
        .build();
    UserDetails admin = User.builder()
        .username("admin")
        .password("{bcrypt}$2a$10$GRLdNijSQMUvl/au9ofL.eDwmoohzzS7.rmNSJZ.0FxO/BTk76klW")
        .roles("USER", "ADMIN")
        .build();
    return new InMemoryUserDetailsManager(user, admin);
}

for more details check the docs.
