Many people find that passwords generated by a password generator are still rejected by websites, or they simply can't remember them. The problem often lies in the custom settings. Don't worry, let's go through it step by step to figure out the most reliable way to set it up.
Where the Problem Lies: Why Are the Generated Passwords "Not Good"?
A password generator is a good tool in itself. It's like a professional random number machine that helps you break out of old routines like "123456". But the issue is that sometimes we set too specific "requirements" for it, which prevents it from performing well.
There are two most common extreme cases: One is being too rigid. For example, you check "must include uppercase letters, lowercase letters, numbers, and special symbols," and set the length to over 16 characters. The generated password is indeed strong, but many website registration forms have character limits (e.g., they don't support certain special symbols), or you simply can't input and remember it. The other is being too lax. For example, generating only pure numbers, or a length of only 6 characters. This is like asking a professional chef to only make plain water. The tool's capability is greatly limited, and the generated password is naturally easy to crack.
So, the core contradiction is: the tool's "random high-strength" attribute is not balanced well with our "usability convenience" or "website rules."
The Right Approach: Three-Step Setup to Generate Good Passwords
Don't be intimidated by those complex options. You only need to focus on a few key points. Taking efTool's password generator as an example, you can operate it like this:
Step 1: Clarify the Password's Purpose and Decide on Length
- What to do: Think about which account this password is for. Is it for an important email, bank, or a普通 forum?
- Where to do it: In the "Length" setting area of the tool.
- What to note: For important accounts (like email, payment), it's recommended to set it to 12-16 characters; 8-12 characters is enough for普通 accounts. Length is the foundation of security. Too short (e.g., below 6 characters) carries high risk.
Step 2: Adjust Character Types to Balance Security and Compatibility
- What to do: Select the types of characters to include in the password.
- Where to do it: Check the boxes in the "Character Types" or similar options.
- What to note:
- For general registration, checking "Uppercase Letters," "Lowercase Letters," and "Numbers" is usually sufficient and offers the best compatibility.
- If the website explicitly supports it and you want higher strength, you can add "Special Symbols." But be aware that some website forms might not be able to input certain special symbols (like
@,#,$, etc.). After generation, you can try copying and pasting it into the input box first. - Avoid selecting only a single type (e.g., only numbers), as this will significantly reduce security.
Step 3: Generate, Check, and Save
- What to do: Click the generate button, view the result, and copy it to the password field.
- Where to do it: In the generated result area.
- What to note: After generation, you can roughly check if the password meets your expectations (length, type). If not, go back to adjust the settings and regenerate. Remember to save the generated password properly. You can use a password manager or keep it in a place only you know.
Several Common Follow-up Questions
Q: How should I save and manage the generated password?
A: For high-strength random passwords, the most recommended way is to use a professional password manager (like Bitwarden, 1Password, etc.) to store them. They help you securely encrypt and save all passwords, and you only need to remember one master password. If you don't use a manager for now, you can save it in an encrypted note-taking app or a local file, avoiding plain text notepads.
Q: Can I customize rules? For example, the first character must be an uppercase letter.
A: Most general-purpose password generators (including this one from efTool) mainly offer basic choices for types and length, and do not support very complex custom rules (like specifying character positions). Its core advantage is "complete randomness." If you need specific rules, you might need more professional password generation software or scripts.
Q: What's the difference between free and paid tools?
A: The password generator from efTool, for example, has completely free basic generation functions, meeting daily needs. Paid tools might offer more advanced options, such as more complex rule customization, batch generation, or deeper integration with password managers. For most individual users, free tools are sufficient.
Q: Are the generated passwords absolutely secure?
A: There is no absolute security. A password generator can greatly enhance the randomness and strength of passwords, resisting brute-force attacks. But security is a system, which also includes avoiding password leaks (not entering passwords on insecure websites), enabling two-factor authentication, etc. A good password is an important part, but not the whole picture.
When Not to Use It, and Alternative Solutions
This password generator is best suited for the scenario: You need to quickly create a high-strength, random password for a new account or an account that needs updating.
But in the following situations, it might not be the best choice:
- You need a "memorable" password: If you want the password to be based on a memory point (like a birthday, pet's name) but still want to increase strength, then a completely random password is not suitable. You can consider using the "passphrase" method, for example, combining several random words (like
CorrectHorseBatteryStaple), which is both memorable and relatively secure. Password generators are usually not good at generating this type of password. - You need to handle other security operations related to passwords: For example, you need to generate signatures for API requests in development, or you need to encode/decode some link parameters. In this case, a password generator won't help.
- If you're handling special characters in URL links to avoid parsing errors, you can use the URL Encoding/Decoding Tool.
- If you need to perform data integrity verification or API signing, you can use the HMAC Hash Calculation Tool to generate message authentication codes.
Remember, tools are static, but usage is dynamic. Understand its core capability (generating random high-strength passwords) and flexibly adjust the settings according to your actual scenario, and it will become a capable assistant in protecting your account security.
