This password generator is provided by Hesapstan for users who want to create strong random passwords in the browser and understand password length, character types, entropy and security level.
What does this password generator do?
This tool generates a random password based on the selected length and character types. The password is created in your browser and is not sent to or stored on a server.
- It allows password length between 8 and 64 characters.
- It supports uppercase letters, lowercase letters, numbers and special characters.
- It can exclude ambiguous characters such as 0, O, 1, l and I.
- It displays estimated entropy in bits.
- It classifies the generated password as weak, strong or very strong based on entropy.
- It uses the browser’s secure random number generator when available.
Generating a strong password is not enough by itself. Do not reuse it, store it in a trusted password manager and enable multifactor authentication for important accounts when possible.
How do you create a strong password?
A strong password is usually long, random and unique to one account. Length often matters more than simply adding one symbol to a short password.
- Use 16 characters or more when possible.
- Use a unique password for every account.
- Avoid names, birthdays, phone numbers and predictable words.
- Do not store passwords in plain text notes or messages.
- Use 2FA/MFA for important accounts instead of relying only on a password.
As password length increases, the number of possible combinations grows quickly. This makes random passwords harder to guess or brute-force.
How long should a password be?
This tool generates passwords from 8 to 64 characters. Eight characters should be treated as a minimum, while longer random passwords are better for important accounts.
Modern password guidance emphasizes length and recommends allowing long passwords. For users, a random password of 16 characters or more is a stronger practical choice for many everyday accounts.
Adding a symbol to a short password does not necessarily make it strong. Consider both length and character pool when evaluating password strength.
What do character type options mean?
Character type options define the pool from which the password is generated. Using uppercase, lowercase, numbers and symbols together expands the random combination space.
- Uppercase: adds A-Z characters.
- Lowercase: adds a-z characters.
- Numbers: adds 0-9 characters.
- Special characters: adds symbols such as !@#$.
- Exclude ambiguous characters removes characters that are easy to confuse visually.
Excluding ambiguous characters can make a password easier to read, but it slightly reduces the character pool. Increasing length can help balance this.
What is password entropy?
Password entropy is an approximate measure, in bits, of how hard a password is to guess. This tool estimates entropy from password length and the selected character pool.
The idea is simple: longer passwords and larger character pools increase entropy. This tool marks below 80 bits as weak, 80 bits or more as strong, and 128 bits or more as very strong.
The entropy calculation assumes the password is randomly generated. If a user adds meaningful words, names, dates or patterns, real strength may be lower.
Is the password generated in the browser?
Yes. This tool generates the password in your browser. The generated password is not sent to Hesapstan servers, saved in a database or stored by the tool.
When the browser supports it, the tool uses a secure random number generator. If that feature is unavailable, the tool displays a warning and recommends using a modern browser.
Browser-side generation is good for privacy, but malware, screen recording, keyloggers or an unsafe device can still compromise passwords.
Random password or passphrase?
A random password is useful for accounts stored in a password manager. A passphrase can be practical when the user must memorize the secret.
This tool generates random character-based passwords. If you need to memorize a password, a long passphrase may also be considered, but avoid predictable quotes, personal details or common phrases.
A password manager makes it practical to use a different long random password for every account without memorizing all of them.
Why is 2FA or MFA important?
Multifactor authentication adds a second verification layer beyond the password. This can help protect an account even if the password is stolen.
For email, banking, social media, business and cloud accounts, using 2FA/MFA together with a strong unique password greatly improves practical account security.
Strong passwords matter, but data breaches, phishing and malware can still expose accounts. Important accounts should use an additional authentication layer.
Password generation example
For example, if the user selects 20 characters and enables uppercase, lowercase, numbers and symbols, the tool generates a random password from a large character pool.
If ambiguous characters are excluded, characters such as 0, O, 1, l and I are not used. This can improve readability; increasing length can help preserve strength.
A password generated for one account should not be used on another account. Reuse makes a breach on one service dangerous for other accounts.
Common password mistakes
The most common password mistakes are using the same password on multiple accounts or assuming that a short password with one symbol is strong enough.
- Reusing the same password across accounts.
- Using birthdays, names, phone numbers or favourite teams.
- Saving passwords in plain text files.
- Adding one symbol to a short password and assuming it is safe.
- Sending passwords through email or messaging apps.
- Leaving 2FA/MFA disabled.
- Continuing to use a password after a breach.
What are the limits of this tool?
This tool helps generate strong random passwords, but it does not provide complete account security by itself. Security also depends on storage, reuse, device safety and additional authentication layers.
- It does not store passwords for you.
- It does not check whether a password has appeared in a data breach.
- It does not verify whether 2FA/MFA is enabled on your account.
- It does not detect malware on your device.
- It does not block phishing websites automatically.
- It cannot know every platform’s password rules.
For email, financial, business or identity-related accounts, use a unique strong password together with a trusted password manager and multifactor authentication.
Frequently Asked Questions
How do I create a strong password?
Use a long, random and unique password. This tool generates random passwords in your browser based on selected length and character types and shows estimated entropy.
Does the password generator store my password?
No. The password is generated in your browser and is not sent to or stored by Hesapstan servers.
How long should a password be?
Eight characters should be treated as a minimum. For important accounts, a unique random password of 16 characters or more is usually a better practical choice.
What does password entropy mean?
Password entropy estimates how difficult a password is to guess based on its length and character pool. It is shown in bits.
Is a strong password enough?
Not always. Important accounts should use unique passwords, a password manager and multifactor authentication whenever possible.
