A system and/or method includes facilitating secured chat messaging. An application module can derive a master password-based encryption key from a master password. The application module can generate a data key and encrypt the data key with the master password-based encryption key. The application module can generate a record key for encrypting chat messages of a chat thread and encrypt the record key with the data key. The application module can decrypt the chat messages in the chat thread with the record key, where the record key is decrypted with the data key, and where the data key is decrypted with the master password-based encryption key. The application module can display the decrypted chat messages.
