# Computer Science – Brute Force PIN Search Interactive Simulator | Cybersecurity & Algorithms Works

Introduce students to the concept of brute force searching with this interactive PIN Search Simulator.

Ideal for A Level Computer Science, cybersecurity enrichment and GCSE Computer Science extension activities, this resource helps students investigate the mathematical search space involved in guessing numeric PIN combinations.

What can students explore?

Students can compare 4-digit, 6-digit and 8-digit PIN search spaces, investigate the number of possible combinations and explore hypothetical time estimates for different guessing rates.

The simulator includes a bounded animated demonstration to help visualise systematic searching. It is an educational model and does not attempt to access real accounts or bypass security systems.

What’s included?

• Interactive offline HTML PIN search simulator
• Printable student worksheet (PDF)
• Teacher guide with classroom activities (PDF)
• Teacher answers and extension guidance (PDF)
• Instructions and customisable licence template

Why use this resource?

Excellent for discussions about password security, computational complexity, search algorithms and the mathematical importance of longer PINs.

Suitable for cybersecurity lessons, coding clubs, independent learning, classroom demonstrations and enrichment.

Works completely offline. No installations, accounts or internet connection required.

Independently developed Computer Science teaching resource.
