Login credentials are an indivisible part of internet users. Credentials are a mechanism that provides proof of an authorised person and, at the same time, prevents personal data abuse by unknown users. The number of passwords that a user has to remember has increased significantly in recent years. There are tools (password managers) available that simplify this problem and are easily accessible. However, the adoption of password managers is still weak.

The goal of this thesis is to identify problems that affect the usability of password managers and attempt to offer a solution to these problems. The analysis also includes an inspection of security and usability vulnerabilities that current password managers suffer from. In the last part, an example of password manager is designed and implemented, which provides important functions and should be accessible and easy to use by all Internet users.
