Secure Password Generator - SafePass.guru: Generate Random Passwords

Create Safe and Secure Passwords

Welcome to the Password Generator – a powerful tool designed to provide you with highly secure and unique passwords for all your online accounts. We understand the importance of safeguarding your digital presence, and our user-friendly interface allows you to customize passwords based on your preferences and requirements.

Choose Password Length

Begin by selecting your desired password length using the slider or simply inputting the preferred number directly into the field. Longer passwords typically offer greater security, so we recommend a length of at least 12 characters.

Choose Characters

Tailor your password by choosing the character types you wish to include:

Uppercase: Includes uppercase letters (A-Z).
Lowercase: Includes lowercase letters (a-z).
Digits: Includes numbers (0-9).
Symbols: Includes printable ASCII special characters.

Choose Format

Customize the format of your password with the following options:

Easy to Say: Generate passwords that more closely resemble English words, making them easier to pronounce and remember.
Easy to Read: Avoid ambiguous characters like 'I' and 'l' for improved readability.
URL Safe: Omit characters that may cause issues in URLs, ensuring your password remains compatible with web addresses.
Filename Safe: Similar to URL Safe, but optimized for filenames.

Note: Remember to keep your passwords safe and do not use them directly in URLs. If required, consider utilizing our UUID generator to create unique identifiers for filenames or URLs.

Password Strength

Assess the strength of your password using our password strength indicator. The strength is depicted by a colored bar ranging from red (weak) to yellow/orange and green (strong). Additionally, the following values provide a numerical representation of the password's robustness:

Score: Ranges from 0 to 100, with 100 being the strongest. Aim for a high score to maximize security.
Entropy: A measure of the password's unpredictability and complexity. Higher entropy means greater difficulty for attackers to crack the password.
Max Entropy: Displays the maximum achievable entropy based on the selected password length and printable ASCII characters.

Generated Password Display

Your customized password will be displayed at the top of this page. To regenerate the password with your chosen options, simply click the "Regenerate" button. For added convenience, you can copy the generated password to your device's clipboard using the "Copy" button.

UUID Generator

A UUID - Universally Unique Identifier (or GUID - Globally Unique Identifier) is a 128-bit unique identifier used to distinguish objects or entities across various systems without any risk of collision. Each UUID consists of 32 hexadecimal characters, typically displayed in five groups separated by hyphens. These groups represent different sections of the identifier.

UUIDs are crucial in ensuring data integrity, as they guarantee the uniqueness of each identifier, even when generated from different sources or at different times. The probability of two UUIDs being the same is practically nonexistent, making them highly reliable for applications like database indexing, distributed systems, and various other scenarios.

We utilize a robust and reliable implementation to generate unique UUIDs. Our method ensures the highest level of uniqueness and security for your identifiers.

The implementation takes advantage of modern browser capabilities and cryptographic functions to create UUIDs with an extremely low chance of collision. Let's take a closer look at how it works:

Using crypto.randomUUID()
If your browser supports the crypto.randomUUID() function, it directly leverages this built-in method to generate a cryptographically secure UUID. This approach guarantees a high level of uniqueness and eliminates any concerns about duplicate identifiers.
Using URL.createObjectURL()
In case the crypto.randomUUID() function is not available, the implementation falls back to the URL.createObjectURL() method to create a UUID. It generates a random UUID by creating an object URL for an empty Blob and then extracting the last 36 characters from the URL. While not as secure as crypto.randomUUID(), it still provides a reasonably unique identifier.
Fallback Algorithm
As a last resort, if neither of the above methods is supported, the implementation employs a fallback algorithm based on random number generation. It uses a combination of bitwise operations and random values to create a 128-bit UUID. While this method may have a slightly higher chance of collision compared to the previous two, it still offers a good level of uniqueness for most practical purposes.

Rest assured that regardless of the method used, your generated UUIDs will be well-suited for various applications, such as database indexing, distributed systems, and more.
