Cetus Dex v2 is a free iPhone app designed to help users create strong and customizable passwords to enhance security. It features a random password generator that allows users to include or exclude specific character types, such as lowercase letters, uppercase letters, numbers, and special characters. Users can easily adjust the password length from 4 to 50 characters using a convenient slider. Additionally, the app offers advanced options like random case mixing and the ability to generate pronounceable passwords, making it easier to remember secure passwords.

The app also includes user-friendly features such as a password strength indicator, which visually evaluates the strength of generated passwords, and a history feature that saves previously generated passwords for future reference. An auto-copy function simplifies the process of using new passwords, and users can also manually copy passwords as needed. For added convenience, Cetus Dex v2 allows users to generate QR codes for passwords, enabling secure sharing and easy input.
