Why old passwords are a risk today!
Many people still use passwords that are years old—perhaps the same one for their university login, personal emails, or cloud storage. The issue? What was once considered “secure enough” can now be cracked in minutes, thanks to far more powerful hardware, advanced algorithms, increased computing power, and even AI-driven attacks.
According to a 2025 study*, an eight-character password using only lowercase letters can be cracked in just three weeks with modern hardware. However, if uppercase letters, numbers, and special characters are added, the required time increases dramatically—up to hundreds of years, provided the password is long enough and sufficiently complex.
But: Just because a password contains complex characters doesn’t automatically make it secure. If a password has ever been leaked (published on hacker forums), includes simple words, or is reused across multiple accounts, it can be cracked much faster using dictionary or combination attacks
Old passwords are often weak because:
- Older passwords were often chosen with only 6–8 characters, frequently using just letters. However, the number of possible combinations increases with each additional character—longer is always better.
- Using only lowercase letters is especially risky; the more character types you include (uppercase/lowercase letters, numbers, special characters), the harder it is for attackers to crack the password.
- Reusing the same password across multiple services or using words that are easy to find online makes an attacker’s job much easier.
- Hardware performance is advancing rapidly, and cracking tools are becoming more efficient. As a result, the standards for what is considered "secure" today are constantly evolving.
What can you do to make your password secure?
- Use passwords with at least 12–13 characters, or even more if possible.
- Include uppercase and lowercase letters, numbers, and special characters. A good trick to remember a complex password is to create a mnemonic sentence where each character corresponds to the first letter of a word.
- Example: “My new Password from 2025 is secure! And not crackable in 5 minutes!” becomes MnPf2025is!&nci5m! (Please don’t use this example—create your own sentence instead.)
- Check your passwords for security and change any that are weak (e.g., too short). You can also find password security tips on our online flyer.
- Use different passwords for different services; a password manager can help you with this.
If your password at the University of Bayreuth is already old, too short, or does not contain any special characters, you can change it yourself in the ITS Portal.
By choosing a strong and well-designed password, you not only protect your university account but also your personal data.

Well aged :
From helpdesk to retirement
After more than 42 and 30 years of service, two long-time colleagues – Jürgen Sturm and Ronald "Ronny" Schönheiter – are retiring this year. Both have been reliable points of contact at the ITS helpdesk, not only for all staff and students of the University of Bayreuth but also for their colleagues within the ITS team.
After such a long time, we couldn’t just let them go without asking them a few questions first:
What was the most interesting project during your time at the ITS?
Jürgen Sturm: The PC Garage: establishing a hardware and system software support service exclusively for students’ personal devices – a project that has been successfully continued for many years by two very capable colleagues.
How did I maintain motivation and commitment during my time at the HRZ/RZ/ITS?Jürgen Sturm: It was always rewarding to find the best possible compromise between local possibilities and fundamental guidelines to address users’ needs and problems.
What were the most significant changes during your time at the ITS?
Jürgen Sturm: Over the course of my 42 years at the University of Bayreuth, IT has evolved from the simplest beginnings—decentralized, modular 8-bit computers with 64 KB of RAM and 360 KB floppy disks, no networks, and mainframe access at RRZE only via punch card readers—into today’s advanced systems. Alongside this, the university computing center transformed into an IT service center, supporting the now ubiquitous and indispensable IT. Unfortunately, the skilled work of colleagues who continue to develop and maintain this infrastructure has largely gone unnoticed.
What lesson would you pass on to younger colleagues?
Jürgen Sturm: The use of critical cloud infrastructure should be undertaken only when it does not create medium- or long-term dependencies regarding data protection, data availability, or costs.
Ronny, what was the greatest challenge you faced during your time at the ITS, and how did you overcome it?
Ronald Schönheiter: Thirty years, from 1995 to 2025: from the University Computing Center to the Data Center, then to the IT Service Center—and now the ITS. As the names suggest, the only constant during this time has been continuous change. Hardware, operating systems, software, services, and tasks—IT is always in flux, with something new constantly emerging.
To draw a bit of a conclusion: the greatest challenge for me—and really for all of us—was not just keeping up with the changes, but always staying one step ahead in order to assist users with their questions and problems and to develop solutions that allowed us to handle the ever-growing number of requests more quickly and efficiently.
Of course, that requires a considerable amount of motivation—so how can one maintain it over such a long period?
Ronald Schönheiter: That only works if you don’t lose the fun and interest in your work, and it also requires a good sense of humor. Equally essential is having a strong service team and good colleagues in other departments, because larger problems can only be solved as a team—IT is not a one-man show; due to its complexity and scope, it only works collaboratively. I can only thank my colleagues for the excellent and collegial cooperation throughout this time.
As parting words, I would like to quote Douglas Adams:
So long, and thanks for all the fish
So many years at the ITS—we want to say THANK YOU for your dedicated and committed work. We wish you a wonderful transition into retirement and many carefree moments ahead.

Attention: Windows 10 Support Extension Not Available for University Computers
Microsoft recently announced a free one-year extension of support for Windows 10, until October 2026. However, this extension applies only to private use with Windows 10 Home or Pro. For the Enterprise version used at the University of Bayreuth, no free extension is available.
This means that all university computers still running Windows 10 Enterprise must be upgraded to Windows 11 by October 14, 2025 at the latest. Only then will full security and functionality support continue to be guaranteed.
