How Long Does It Take to Crack Your Password? (2025 Benchmarks)

Introduction

When you type your password into a website, you assume it's safe. But security is a race against time—and hardware.

Every year, graphics cards (GPUs) get faster. The same technology that makes video games look photorealistic is also used by hackers to guess billions of passwords per second. A password that was "secure" in 2020 might be cracked in minutes today.

In this guide, we are looking at the 2025 benchmarks. We'll show you exactly how fast a modern rig can break into your account, and why length is your only defense.

⚠️The Reality Check

A single modern gaming GPU (RTX 4090) can guess 164 billion NTLM passwords per second. A hacker doesn't need to be a genius; they just need good hardware.

The Moore's Law of Hacking

Moore's Law states that computing power doubles roughly every two years. For password security, this is a nightmare.

Ten years ago, cracking an 8-character password took centuries. Today, with a cluster of 8 GPUs, it takes less than an hour. Attackers use tools like Hashcat to automate this process, running through every possible combination of letters, numbers, and symbols until they find a match.

The 2025 Hardware Benchmark

Let's look at the numbers. Security researchers measure speed in "Hashes per Second" (H/s).

The Weapon: A dedicated cracking rig with 8x NVIDIA RTX 4090s.

Cost to build: ~$15,000 (accessible to organized crime groups).
Speed: ~1.3 Trillion guesses per second (MD5).

🔑Key Takeaway

Hackers don't attack your login page; they attack the database. Once a website is breached and the password hashes are stolen, they can crack them offline as fast as their hardware allows, with zero rate limiting.

Here is how long it takes that 8-GPU rig to brute force different passwords using the MD5 hashing algorithm (common in older systems).

Length	Numbers Only	Lowercase Only	Upper + Lower + Numbers	Complex (+ Symbols)
8 Chars	Instantly	Instantly	Instantly	39 Minutes
10 Chars	Instantly	Instantly	3 Days	5 Years
12 Chars	Instantly	2 Hours	3,000 Years	3 Million Years
14 Chars	Instantly	1 Year	200m Years	Quintillions

The takeaway is clear:

8 characters is dead. Even with symbols, it's gone in under an hour.
12 characters is the new baseline. Even a complex 10-character password is risky if the attacker has enough budget.

The Difference Between Hashing Algorithms

Not all websites store passwords the same way. The "Hash" is the mathematical fingerprint of your password.

Fast Hashes (MD5, SHA-1, NTLM): Designed for speed. Terrible for passwords. These can be cracked in seconds. Unfortunately, many legacy corporate systems still use them.
Slow Hashes (Bcrypt, Argon2): Designed to be slow. Cracking these is painful for hackers. Even an 8-GPU rig might only guess a few thousand Bcrypt passwords per second.

Quick Tips

Use a Password Manager: It generates 20+ character random passwords that are mathematically impossible to guess.
Enable 2FA: Even if they crack your password, they can't get past the second factor.
Check your old accounts: Use "Have I Been Pwned" to see if your old, short passwords have already been leaked and cracked.

How to Beat the Mathematics

You cannot stop computers from getting faster. But you can stay ahead of the curve.

Every character you add multiplies the difficulty. Moving from 8 characters to 12 characters doesn't make it 50% harder; it makes it millions of times harder.

Don't try to be clever. Be long. A 15-character password made of simple letters is practically invincible against brute force attacks today, tomorrow, and for the next decade.

Conclusion

The days of memorizing an 8-character code are over. The hardware is simply too fast.

If your password strategy relies on "hoping nobody targets me," you are gambling with your digital identity. Upgrade to 12+ characters (or better yet, a passphrase), enable 2FA, and make the math work in your favor.
