He's only 12-years-old, but he could probably guess the password to your phone.
Cian Tormey from Colaiste Phadraig in Lucan is presenting his research on passwords at the 51st BT Young Scientist and Technology Exhibition.
The whizz kid spent three months investigating why people choose the passwords they do after his Xbox account was hacked last year.
"I am after figuring out why people choose their passwords and how they choose them. Most people choose their passwords so it is relative to them, but they shouldn't," the first year student told the Herald.
"They should have it more random so, just a word or something. I got hacked, someone hacked me on Fifa. "They bought €40 worth of stuff, and my dad had to cancel his credit card. We got all our money back," he added.
"It took me around three months to do the project, it was hard because I was doing it by myself. My dad helped me give out my survey," he said.
More than 18,000 visitors flocked to the RDS in the capital yesterday, as the doors opened to the public for the first time on the second day of the prestigious annual competition.
Many of them were impressed by the work of aspiring scientists Martha NicIonais and Caoilfhionn Ni Dheorain.
The 14-year-olds are second year students in Colaiste Chilliain in Clondalkin.
They used the advances they have made in science to help educate some of the younger students in their school, including a 3D printer which they built with help from their technology teacher.
Using their printer, they made printed dices, small pyramid shapes and earphone cases.
"We started in October in first year, and ended just before the summer break," the pair said.
"Two judges have come so far, they were really enthusiastic."
The winners of this year's competition will be announced this evening.
