    Password Recovery Insight

    This password is moderately secure. Recovery may take hours to days with premium GPU Strong Password Recovery.

    Simple Explanation

    Password recovery works by trying every possible combination until the correct one is found. Two things determine how long this takes:

    1. Password Length

    Longer passwords = more combinations to try. Each extra character multiplies the possibilities.

    8 characters
    100M combinations
    12 characters
    1T combinations

    10,000x more!

    2. Character Types

    Using numbers, letters, and symbols increases complexity. More character types = harder to crack.

    Only digits (0-9)
    10 options
    All characters
    95 options

    9.5x harder per character!

    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:

    8 characters

    vulnerable to GPU

    Can be cracked in seconds to minutes by professional password recovery services

    10 characters

    difficult but possible with extended GPU Strong Password Recovery

    May take hours to days for GPU-accelerated password recovery

    12+ characters

    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

    1. Simple Passwords
    • Short
    • Contain only digits or letters
    • Often represent dictionary combinations

    Such passwords are recovered quickly — sometimes in seconds or minutes.

    2. Complex Passwords
    • 10+ characters
    • Random
    • Use full ASCII set

    Recovery time can vary from several days to impossibility of GPU Strong Password Recovery in principle.

    Conclusions

    1. Length is the decisive factor.

    Each added character increases recovery time by an order of magnitude.

    2. Symbol diversity dramatically increases resistance.

    Using numbers, uppercase, lowercase, and symbols makes passwords much stronger against password recovery attacks. This applies to ZIP, RAR, PDF, and Office file passwords.

    3. Dictionary words break instantly.

    That's why human passwords are the most vulnerable.

    4. Secure password — 12+ random characters.

    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.
