![]() ![]() But you know what’s worse than a password? A fingerprint. Nobody picks good ones, when they do they re-use them across sites, and if you use even a trustworthy password manager, they’ll get hacked too. If you're an activist, journalist, or anyone else who might have sensitive contact information or communications on your phone, the law will be on your side if a member of law enforcement asks you to unlock it.Passwords are crap. If, however, you're in the United States, and you're worried about the government getting into your phone, you may want to stick with a PIN. As such, while fingerprints are safer, there's nothing inherently wrong with using a PIN code. Breaking a PIN code can be long, arduous, and expensive, and many hackers may not bother unless you're a high-profile citizen. In comparison, it's impossible to brute-force a fingerprint.Įven if you do decide to stick with a PIN, it's highly unlikely you'll suffer an attack. Without the 10-attempt erasure, your PIN is subject to brute-force attacks which will eventually crack it. Even with the 10-attempt erasure feature turned on, it's possible-however unlikely-that someone could guess your PIN. This attack took advantage of an old bug, and wouldn't work anymore, but it shows that no system is perfect.įor the vast majority of people, a fingerprint will be the more secure way to go. There was a hack for the iPhone which powered it off after an incorrect PIN entry, so the wrong-guess counter didn't increase. Pattern locks are stronger than PIN codes in this regard, but unfortunately, research showed that pattern codes aren't very secure.Įven with protection against a brute-force guessing attack, someone might be able to get in if they're highly motivated. There are only so many different four- or six-number PINs you can create. It could be a very long time, but with an infinite number of guesses, any person or computer would eventually get it. Without extra security features, cracking a PIN is only a matter of time. As soon as a PIN code is compromised, you can set a new one and forget the old number. If someone created a recreated model of your print, there's not much you can do to protect yourself. ![]() If not, they're out of luck unless they can hack it another way.Īlso, unlike a fingerprint, PIN codes are changeable. If you have something like this on your phone, anyone trying to crack their way in would have to have some excellent guesses to make it work. ![]() This benefit means fewer lock-outs from your phone and less time spent trying to hack your way back in. Forgetting a PIN is annoying, but it's impossible to misplace your fingers. Using a fingerprint scanner is the quicker and easier option for chronic phone-checkers.įingerprints are also fantastic for people with bad memories. If you're always unlocking and locking your phone, entering PIN code can get annoying. It's also one of the quickest methods of authentication. It's a simple way to improve your security. As such, fingerprint phone locks are the best choice against prying eyes. The most significant benefit of fingerprint scanners is how they can't be leaked "over the shoulder." Someone could quickly look at your phone as you enter your PIN and learn your code, but they can't do the same with a fingerprint. They feel secure and are convenient, but they're not perfect.
