Sometime i have to process two questions below: 1. Account must be change password every 3 or 6 months. 2. I need to register a new account to avoid likes recommendations Everytime i changed or create new safe password, it’s make my mind like a storm.

If you have same question like me, this tool maybe help you.

  4. paste it to this tool, and click ‘save’ website
  5. click listview which named like your url, password will be copied to clipboard copied
  6. paste your password to anywhere you want.

By the way, step.4, it could use any information to save, for example, you could use three types of web page like below: 1. 2. 3. this is account for website

This info just to make you know, which item in list is password you need copied.

  2. desc.txt
  3. pin.txt

  1. If you are flutter developer, you should changed AES sign and rebuild your own application, it will have more security.
  2. Don’t use simple web url to paste, like, it maybe same with others. better choice is use url on register page, most web service will generate unique page for register to trick user data.
  3. Don’t copy file to other platform, use sms login by phone, use this for computer login, is better way.
  4. Don’t put all your secret here, it should only saved password which updated many times or password not important
  5. Don’t use this on other people’s device!
