There are large companies out there (example: Orbia) who explicitly recommend ONLY using LastPass as a password manager to their employees "for security".
LastPass will remain dominant until someone else with similar functionality offers a free tier. 1Password is similar functionality, but you have to subscribe after 14 days and that drives alot of people away even if they can afford it. And so LastPass has most of the mind share, and thus most of the sales.
Bitwarden has been offering similar features with a very generous free tier for years now.
Speaking of the Rise and Fall of password managers, Bitwarden has served me well for years but lately it has started to get reallly slow for my friends and I. Is there a newer cooler kid on the block?
Lastpass has been sketch for years but AOL was still making money thanks to those CDs and email addresses last I checked. My chase card also recommends lastpass in their app’s shopping section.
