I like to type out a random set of numbers and letters and save them to a notepad. It's the best defense against brute force attacks. The bitcointalk hack that happened in 2015 wouldn't have been a problem for anyone if their passwords were good because all the passwords needed to be bruteforced.
Is that okay to save your password on a notepad? If talking about hassle to input really long passwords with signs, numbers and letters with Caps it was tiring but keeping it away from your notepad makes it safer. i just really get this idea since this was a rule of thumb given by professionals in the industry.
