When users register on the site, their passwords in the database are generated as follows, for example: $2y$10$p4KT1nRL5uUxS9nfxNh7zOc6jvMMJQEN6wlibUGMxKevGj0Xu6ZUi. What type of encryption is used for this password? If I want to change the password, how can I do that? It's not md5, and I can't figure it out.
