Most of us use loads of services where a login is required. Therefore we have passwords that we have to remember. As it is bad practise to use the same password everywhere, it might become difficult to remember all the difficult combinations. So I decided to use an Arduino to automate the password-typing process and stored the password securely in the microcontroller. Note that once a microcontroller has a sketch in it, it is impossible to access any information within the uploaded sketch and so hackers can't get access to the passwords stored in the microcontroller's memory.
The device looks like this:
It doesn't have any power source inside, which is not necessary, because it only works in combination with the computer. In this project I have used the Arduino Pro Micro because of the ATmega32U4 chip that already has built in USB.
To connect the device to the computer we need a standard smartphone charging cable (USB micro).
Once connected you have to type in only one password to get access to the other ones. You can change it in the sketch. The password is the rotation clicks of the encoder in the right direction the right number of times. It is difficult to understand, just watch the video to see what I am writing about)
Use the encoder to navigate through the menu and press the encoder to enter password into the computer.
Here is the video where I am building it. Watch it please and leave a like!
This really supports me.
