alt Hacker NewsPassword managers (whether it's Lastpass or your browser's built-in password store) also protect against phishing since they tie passwords to domain names.
I don't think password managers which store encrypted vaults are less safe than trying to have and juggle strong unique-per-domain passwords, even if you think that the password manager is becoming a target.
When they work… I finally gave up on 1Password as it has been getting worse and worse about actually autofilling for a few years. After all the Avengers turned into investors and the price increase was announced, I jumped ship. It felt like they were more worried about their ROI than the product. After 18 years of use, this was pretty disappointing.
