One way to create strong and secure passwords is to use the free online tool "Password generator" from www.darkbit.xyz. This tool allows you to generate passwords with custom length and custom settings. You can choose the type and number of characters, such as lowercase, uppercase, digits, symbols, or even custom characters. You can also exclude similar or ambiguous characters, such as 0 and O, or l and I. The tool will generate a random password that meets your criteria and display it on the screen. You can copy the password to your clipboard or save it as a text file.
