“Now you don’t have to remember any of your passwords, and they are still safe and ready to use!
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.”
