Faced first hand the disadvantage of having different password for different platforms or medias
Don't let this experience sway you towards bad password habits. It's a very good thing to use a different password for each online account. I mean, it's almost a given that you'll be affected by a data breach at some point, and when that happens, you don't want it to cascade into multiple problems, and you really don't want it to result in your e-mail account(s) getting compromised, too, because then you're up shit creek without even a canoe.Haven't found a proper solution yet but I believe am more tempered than before.
Use a password manager. (An offline one like KeePassXC, and remember to back up the database file once in a while, too.) 
Never tried password manager but will do now
Always thought it could be easily compromised but I'm just learning there are offline ones now.
