Its simply the best defense!

First, you really really know you need to move to a complex password - and will require memory assistance to recall them, otherwise why are you looking at password vaults. That you are here is a good thing! I have nearly 800 passwords and I only need to recall one, 1Password handles the other 799.
Second, please hit the reviews STARS count for this version, then ALL versions. You will notice 1Password has about a 4.95 out of 5 score, with nearly 20,000 reviews. More importantly, notice the negative stars trends over time... diminishing! Thats the secret sauce 1PASSWORD just keeps getting better!
Third, its inexpensive, cross platform, integrates with your browsers (the s entirely intentional, we all typically use more than one browser these days), and can back up to a local volume as well as a number of secure cloud sites (remember to ALWAYS use 2 factor login to cloud volumes!).
Fourth, have a family, or team? 1Password supports secure sharing of 1 or a set of passwords. Easy to share with the wife the password to the bank account or Netflix with the kids!
Fifth, want to know if one of you bezillion sites has been compromised? And you need to up date a password? The integrated Watchtower feature monitors that for you as well and alerts you to update a password. Easy!
Last, nuf said stop looking - you found the solution, buy it!
