Please used a long strong password (with a password manager such as one within Firefox or as recommended by Rise Up Keepassxc or Bit Warden as discussed recommended on Security Now podcast by TWIT. With a password manager you then just need to remember one long strong primary password, and see J.Mann's Song on choosing this) and consider setting up Two Factor Authentication, where available for logging into websites and apps. Note: QR codes and time based secrets can be used in multiple Auth apps, onmultiple devices whihc is worth doing just in case lose the device.
