Why to use it

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.

How to use it

input your pin code when first start.
click Name and Description to input anything you want.
open your account changed & register web page and copy webpage url
paste it to this tool, and click 'save'
click listview which named like your url, password will be copied to clipboard
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. https://test.com 2. test.com 3. this is account for test.com website

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

Suggestions

If you are flutter developer, you should changed AES sign and encrypt & decrypt method, and rebuild your own application, it will take more security.
Don't use simple web url to paste, like www.google.com, 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.
If you want to use on other platform, just copy file to right directory.
Don't put all your secret here, it should only saved password which updated some times or unimportant
Don't use this on other people's device!

End

this software is free, if it help you, please give me your stars. thanks.
