1Password creates strong, unique passwords for all of your sites and logs you in with a single tap (or click). A single click opens your browser, opens a site, fills in your username and password, and logs you in. Our Strong Password Generator is your key to password liberation. One click creates a strong, unique password for each account, and our browser extension fills it into the website automatically.
- 1Password is proprietary (not open source) and might not encrypt your URLs (neither does LastPass). A more trustworthy choice is KeePass (or KeePassXC for Mac/Linux with browser integrations). Failing that, try BitWarden, which syncs just like 1Password, except that it's open source and does encrypt your URLs.
- Although it is not Open Source (and usually when you want an alternative to an OS software, you would naturally wish for another OS solution) you can just purchase the applications and you are done. No monthly fees (although 1Password does have a plan option) and has a local database (unless you wish to sync between multiple devices). I also think it is above KeePass due to the extensions, which improve your daily routine quite significantly.
