If you're not using a password manager then you're mostly likely 1 data breach away from not knowing how many other accounts of yours have been compromised.
They're so incredibly easy to use, they're all basically free, and they are essential IMO. I personally use Bitwarden, before that was LastPass until they first got rid of any reason to use the subscription, only to then lock multi-device use behind the subscription (oh and they got bought by LogMeIn, who are a garbage company). Bitwarden is better in every way, so it was a win. Happily paying for Bitwarden, and would recommend it to everyone.
I've used bitwarden for a number of years for personal use. My job uses 1Password which I've used for 7 months.
In features they are very similar.
Bitwarden has more granular URL matching (can use regex to match websites) whilst 1Password is weaker in this area (can do subdomain but no URI matching, no wildcard or regex).
1Password UX is much better, certainly feels like a paid for service.
1Password is much more expensive (monthly subscription)
1Password 2FA can read QR codes from the screen and automatically puts the code into the website. Bitwarden needs the QR text pasting into the password entry and puts the code into clipboard when the password is used.
Bitwarden can be self hosted (Vaultwarden).
Overall I think I prefer 1Password but not enough to pay the subscription. Work do give me a free personal account but I don't like relying on small possible temporary benefits. So I stick with bitwarden. I pay the $10 a year and I'm happy.
