Password Recovery Chances: How Length and Character Set Affect GPU Strong Password Recovery Success
Password recovery through GPU Strong Password Recovery is a mathematical process that depends only on two factors: password length and character set size. Understanding these factors helps assess how complex a password is and how much time services like LostMyPassPro will need to recover it.

Password Recovery Time Calculator
Calculate how long it takes to recover your password. Enter password length and character types to see recovery time with our GPU-accelerated service.
Simple Explanation
Password recovery works by trying every possible combination until the correct one is found. Two things determine how long this takes:
Longer passwords = more combinations to try. Each extra character multiplies the possibilities.
10,000x more!
Using numbers, letters, and symbols increases complexity. More character types = harder to crack.
9.5x harder per character!

Based on modern GPU (1 billion combinations per second)
Quick Comparison Table
Recovery time for 8-character passwords by character set (Premium tier: 1B combinations/sec)
| Character Set | Symbols | Combinations | Recovery Time |
|---|---|---|---|
| Only digits (0-9) | 10 | 100.0M | 100 ms |
| Lowercase letters (a-z) | 26 | 208.8B | 3.5 min |
| Mixed case (a-z, A-Z) | 52 | 53.5T | 14.8 hours |
| Letters + numbers | 62 | 218.3T | 3 days |
| All characters (~95) | 95 | 6.6Q | 77 days |
Password Recovery by File Type
Different file formats require different password recovery approaches. Here's what you need to know about recovering passwords from each format.
ZIP Password Recovery
ZIP password recovery is one of the fastest types of password recovery. Our service uses advanced GPU-accelerated technology for direct ZIP password cracking. Simple ZIP passwords (6-8 characters) are typically recovered in seconds to minutes.
- • Supports standard ZIP encryption
- • Fast recovery for common passwords
- • GPU-accelerated brute-force available
RAR Password Recovery
RAR password recovery supports both RAR3 and RAR5 formats. We use advanced hash extraction technology, then GPU-accelerated brute-force for password recovery. RAR passwords are generally more secure than ZIP, requiring more time for recovery.
- • Supports RAR3 and RAR5 formats
- • Professional hash extraction technology
- • Longer recovery time for complex passwords
PDF Password Recovery
PDF password recovery works for password-protected PDF documents. We support PDF 1.4 through 1.7 encryption levels. PDF password recovery time depends on the encryption method and password complexity.
- • Supports PDF 1.4, 1.7 Level 3, and Level 8
- • Advanced hash extraction technology
- • Recovery time: minutes to days
MS Office Password Recovery
Microsoft Office password recovery supports Word (.doc, .docx), Excel (.xls, .xlsx), and PowerPoint (.ppt, .pptx) files. We support Office 2003 through Office 2016 formats. Office password recovery is typically faster than PDF recovery.
- • Supports Word, Excel, PowerPoint files
- • Office 2003 through 2016 formats
- • Faster recovery than PDF documents
What Password is Considered Complex?
From recovery perspective:
vulnerable to GPU
Can be cracked in seconds to minutes by professional password recovery services
difficult but possible with extended GPU Strong Password Recovery
May take hours to days for GPU-accelerated password recovery
beyond practical GPU Strong Password Recovery
Years to impossible to crack, even with professional password recovery services
Ideal password for GPU Strong Password Recovery resistance:
12–16 random characters (a–z + A–Z + 0–9 + special symbols).
What This Means for LostMyPassPro Users
- •Short
- •Contain only digits or letters
- •Often represent dictionary combinations
Such passwords are recovered quickly — sometimes in seconds or minutes.
- •10+ characters
- •Random
- •Use full ASCII set
Recovery time can vary from several days to impossibility of GPU Strong Password Recovery in principle.
Conclusions
Each added character increases recovery time by an order of magnitude.
Using numbers, uppercase, lowercase, and symbols makes passwords much stronger against password recovery attacks. This applies to ZIP, RAR, PDF, and Office file passwords.
That's why human passwords are the most vulnerable.
For real security against professional password recovery services, use at least 12 random characters with mixed types. This makes password recovery practically impossible even for GPU-accelerated brute-force attacks on ZIP, RAR, PDF, and Office files.
