I think I found two great videos on youtube on the dos and don'ts of password creation. A real must watch. I encourage everyone to watch these and then consider if your passwords are really safe.

If you don't trust my link the video is called: "Password Cracking - Computerphile" also "Password Choice - Computerphile "
If you know of a better video on password creation plz post it.
Edit: would also like to recommend everyone watch "How NOT to Store Passwords! - Computerphile" and "Security of Data on Disk - Computerphile"
This reminds me that I should change the passwords on my bitcoin wallets. Though it has a 2fa security and it is very long but since there are only letters in it I guess the hackers could easily hack it. My wallets are always at zero balance but if I dont place a good password on it and suddenly somebody send me a good amount of btc then that would be trouble. Next time when I will make or generate a wallet I will make sure that even I will make it very complicated.
