What is a Bcrypt password?
By default, it uses BCrypt to encrypt the passwords, which is considered a well-rounded algorithm for encoding passwords. It is also possible to set the number of hashing rounds (or the strength as the parameter name suggests) and the secure random algorithm implementation to be used in the process.
What is in-memory authentication?
In-Memory Authentication means using a database that stays in application memory/RAM (one example is the h2 database) to save users and perform the authentication without saving them to a persistent database. Such databases can be useful when you are building a proof-of-concept app or prototyping your application and need to get going or test your authentication code without bothering yourself with a database. An in-memory database is also useful if you run your tests without mocks so that your real database will remain untouched and the changes caused by tests will be in temporary memory.
What is LDAP used for?
LDAP is short for Lightweight Directory Access Protocol, and it is commonly used for authenticating the user accounts of employees in enterprises. It allows you to specify users/user-groups in a hierarchical structure and define their permissions.

In separated frontend-backend architectures, the frontend stores this token in cookies.
Can Spring Security guess passwords?
Spring Security cannot magically guess your preferred password hashing algorithm. That’s why you need to specify another @Bean, a PasswordEncoder . If you want to, say, use the BCrypt password hashing function (Spring Security’s default) for all your passwords, you would specify this @Bean in your SecurityConfig.

Features
- In this section, we are going to direct our attention to the features that Spring Security has and what it can provide us or its use-cases. We are also briefly mentioning the "how" while doing so.
Building Blocks of Spring Security
- In this section, we will take a look at several concepts which are heavily applied in Spring Security. Basic knowledge about these topics will serve as a foundation that we can build upon since all these topics are more or less connected to each other.
Conclusion
- In this article, we have started by defining Spring Security and tried to provide insights about what kind of things a security framework provides. I hope it is more clear after reading the features section and seeing the example use cases for Spring Security. After learning what it is good for, we have taken a look at some important concepts that can help us understand Spring Security b…
