I came to comment about the utility of a password manager, too. I’m glad @Supersonic beat me to the punch! Make sure that if you do use a password manager, you purchase a paid service that doesn’t share your information and that tells you how your data is stored and where their servers are located. I opted for a LastPass premium subscription for $36/year, and it’s fantastic to have on all my devices. You can read reviews of other password managers on PCMag; some notable options include Keeper, LastPass, 1Password, and NordPass.
