A password is a sequence of characters—letters, numbers, symbols—that grants access to an account while blocking others. In today's digital world most of us manage at least one, so learning how to craft a robust password (or rely on a generator) and how to protect it is essential.

Password strength

Password strength indicates how well a password can resist guessing or brute‑force attacks. Generally it estimates the number of attempts an attacker would need on average. Strength depends on length, complexity and randomness; using personal data like names or birthdays typically results in a weak password.

Beyond the password itself, proper security measures greatly lower breach risk. Such controls—like two‑factor authentication or temporary account lockouts after multiple failed logins—detect, deter, or mitigate threats.

How to create a secure password

You can build a secure password by following guidelines aimed at boosting its safety. This involves not only creating a complex password but also rotating it periodically and steering clear of common choices (e.g., “password”, “123456”, “qwerty”). Here are some recommended practices:

• Include lower-case letter(s) [a-z]
• Include upper-case letter(s) [A-Z]
• Include numbers [0-9]
• Include symbols [!@#$%^&*()...]
• Exclude words involving the user's personal information
• Exclude words found in a password blacklist – there are password blacklists that can be found on the Internet, or it is possible that a company / other institution may have their own password blacklists
• Exclude company/institution name, as well as abbreviations of the name
• Exclude passwords that match common formats such as calendar dates, license plate numbers, phone numbers, or other common number formats

Also, many password policies typically include a minimum password length because generally, the longer a password, and the larger the variety of character types, the more secure the password.

Our generator lets you omit ambiguous symbols such as the letters "L" and "I", which can look similar on screen. This is useful because a capital "I" may be confused with a lowercase "l" or the number 1, potentially locking you out. Keep in mind that removing characters can slightly reduce the overall entropy.

Password entropy

The tool also calculates password entropy in bits. Higher entropy means the password is harder to guess. In a brute‑force scenario, 100 bits of entropy would require 2^100 attempts to exhaust every combination; on average an attacker would need about half that before hitting the correct one.

How to protect your password

Safeguarding your password is as crucial as choosing a strong one. Below are some practical steps you can adopt; many more exist, but these guidelines are a solid start:

• Avoid sharing your password—ideally only you should know it. Even trusted friends might be less vigilant about keeping it safe, increasing the chance of unauthorized access.
• Never reuse the same password across multiple sites. While convenient, a breach on one service could endanger all your accounts. A password manager can generate and store unique credentials for each site, simplifying this process.
• Update your passwords often – While it may feel like a hassle, regularly rotating your credentials adds an extra layer of protection. If someone has somehow obtained your current password, a fresh password cuts off their access after a short window, assuming they can't guess the new one. Additionally, swapping out passwords on devices you no longer own (sold, discarded, etc.) prevents a stranger from reusing stored credentials.
• Avoid storing passwords on shared or public machines – The safest practice is to keep your login details off any computer that isn’t yours, which minimizes the chance of an unintended party retrieving them. Likewise, steer clear of logging into sensitive accounts while connected to unsecured public Wi‑Fi networks.
• Don’t keep plain‑text password lists within reach – Whether it’s a sticky note on your monitor, a "passwords.txt" file on your desktop, or a note on your phone, such records can be easily discovered and exploited. Instead, rely on a reputable password manager to keep your credentials encrypted, or memorize strong, unique passwords for each service. Physical notebooks and electronic files are prone to loss or theft, so keeping them out of sight is essential.
