Generate secure, random 10-character passwords. 66 bits of entropy — good strength. Everything runs in your browser.
Use ⌘ + D to bookmark this toolA 10-character password crosses the threshold into reasonable security territory. At 66 bits of entropy, it would take over a century to brute-force with a modern GPU cluster. This length handles most casual threats well, though targeted attacks with dedicated resources could still crack it within a human lifetime.
Entropy is calculated as: length × log₂(pool_size). With 10 characters from the full 95-char printable ASCII set, you get 66 bits of entropy. Brute-force time at 10 billion guesses/sec: 117 years.
50 pre-generated examples. Use the generator above for a cryptographically fresh password — these are for illustration only.
Apple requires at least 8 characters with mixed types. Salesforce requires 8-10 depending on the org policy. Many enterprise systems default to a 10-character minimum. Government systems (FISMA Low) typically accept 10+ characters with complexity requirements.
Instagram, TikTok, Reddit, and similar platforms. These accounts are targets for social engineering more than brute-force, but 10 characters provides solid baseline protection.
Netflix, Spotify, Disney+, and other entertainment accounts. Account sharing and credential stuffing are bigger threats than brute-force here.
E-commerce sites where you've saved a payment method. These should ideally use 12+ characters, but 10 with 2FA is acceptable.
Steam, Epic, PlayStation, Xbox accounts often hold significant value in game libraries and in-game items. Use 10+ characters and always enable 2FA.
| Length | Entropy | Crack Time (GPU) | Rating | Recommended For |
|---|---|---|---|---|
| 6 chars | 39 bits | 3.5 seconds | Weak | temporary or throwaway accounts only |
| 8 chars | 53 bits | 1.3 days | Fair | low-security accounts where the site enforces rate limiting |
| 10 chars | 66 bits | 117 years | Good | general-purpose accounts and social media |
| 12 chars | 79 bits | 1.1 million years | Strong | general accounts |
| 14 chars | 92 bits | 10 billion years | Strong | sensitive accounts |
| 15 chars | 99 bits | 894 billion years | Excellent | business accounts |
| 16 chars | 105 bits | 84 trillion years | Excellent | master passwords |
| 20 chars | 132 bits | 7 × 10²¹ years | Overkill | master passwords |
| 24 chars | 158 bits | 6 × 10²⁹ years | Overkill | maximum security |
| 32 chars | 211 bits | 4 × 10⁴⁵ years | Overkill | encryption keys |
| 48 chars | 316 bits | ∞ | Maximum | cryptographic secrets and machine-to-machine authentication |
| 64 chars | 421 bits | ∞ | Maximum | cryptographic keys |

A 10-character password provides 66 bits of entropy, which offers limited protection. Modern GPUs can crack it in 117 years. For important accounts, consider using at least 12-16 characters.
With a modern GPU cluster computing 10 billion hashes per second, a random 10-character password using all character types (95-char pool) would take approximately 117 years to crack by brute force. Using only lowercase letters would be significantly faster to crack.
Both matter, but length has a greater impact. Each additional character multiplies the total combinations by the pool size (up to 95 for all printable ASCII). However, using all character types (uppercase, lowercase, numbers, symbols) maximizes the pool size, which also multiplies security exponentially.
Yes. You cannot reliably memorize unique random passwords for every account. A password manager securely stores all your passwords behind one strong master password, and can auto-fill them across devices and browsers.
A 10-character password is recommended for: general-purpose accounts and social media. Always use the strongest password practical for each account, and never reuse passwords across sites.
