Personal password managers offer a great convenience to use different passwords everywhere to limit exposure risks when one site or another inevitably gets hacked (see https://haveibeenpwned.com/).
However, they also represent a single point of failure they themselves get hacked.
- Google Password Manager - built-in to the Chrome browser. If Google gets hacked it's game over because everybody relies on Google for GMail and SSO auth logins.
- BitWarden - open-core, free for personal use
- 1Password
- Keeper
- LastPass - don't use this one - they've been hacked before. I'm not even going to provide a link to this.
Secret Managers allow integrations to share secrets between different technologies.
- HashiCorp Vault
- AWS Secrets Manager
- Google Secret Manager
- Azure KeyVault
- CyberArk - enterprise key vault
