It seems to be generally accepted the same password should not be used for different sites or devices. How different should passwords be? For example
+_^gum<JW2 are very similar. Does it matter what the passwords are used for, for example having two e-mail accounts with similar passwords may be poor security but would having an e-mail account and encrypted USB device with similar passwords be better? What if two or more passwords follow a pattern or relation? For example
I have read that all passwords should be random. This is ideal but not feasible.
- It is most difficult to remember and password managers may not be a viable option (for example password to memory stick you carry with you).
- It has been stated that computers should not be used to create random passwords.
- Some devices it's very hard to type long complex passwords in, such as smartphones.
