Abstract. The use of passwords is one of the most popular ways to authenticate users on the Internet. Because of the specificity of storing passwords, developers are forced to impose restrictions on which passwords are safer to use. For example, most often a password must contain at least 8 characters, have letters of different registers, contain special characters, etc. It can be stated that over time, these restrictions only increase, and this in turn complicates the choice of a secure and at the same time easy-to-remember password. For example, the most secure password will contain 128 characters with maximum entropy.

The article is devoted to user authentication, password entropy and valid passwords for websites, methods for improving authentication by developing a hardware password manager based on Arduino microcontroller.

Thus, a password generated randomly has more entropy than a password generated by the user. The algorithm of the device includes functions of generating a password from the permissible characteristics and maximum entropy, storing the password on the device, improving security by confirming actions, reading the password from the device to the input line, and using the pin-code protection.

Key words: password entropy, valid password values, device operation algorithm, password characteristics, microcontroller.
