Anyone with the URL can access it?
Actually, it's quite safe.
"Isn't it risky that anyone who knows the URL can view it?" You might think so. In reality, it's far safer than the username/password combinations most people set themselves.
Why is it safer than a password?
Memotto's security strength, in numbers
In plain terms:Stumbling across your note's URL by chance is about as hard as picking one specific grain of sand from every grain on Earth.
🔬 What about quantum computers? Even with quantum computing, 122 bits only drop to the equivalent of 61 bits. That still requires18 quadrillionoperations, andNIST experts rate it "safe for decades".
Typical password setups
- • "password123" or "1234"
- • Birthdays and names combined
- • Cracked by dictionary attacks in hours to days
- Effective security strength: extremely low
Memotto's cryptographic URL
- • 122 bits of cryptographic randomness
- • 5.3×10³⁶ possible combinations
- • Practically impossible to guess
- Effective security strength: banking-grade
