I don't use ANY third party keeper. I don't want any system that is outside my personal control to have my PWs. I keep a file locally and use my local browser system. Nothing goes outside my house. My phone only has limited access to financial things, mostly for shopping, no banking.
That said, U.S. Government sites have taken to using systems that seem to thwart user security. Office Of Personnel Management (OPM) will not let you paste a password and will not allow password managers, browsers or otherwise to fill in your PW to log in. You must manually type your PW each time. U.S. Treasury Direct is similar, but they require the use of an on-line keyboard, point to a digit or character with your mouse and click it. No pasting, or form fills, no standard keyboard typing. I don't even know my PWs for most sites as they have a mix of letters, numbers and characters. There is no way I could type it each time using either method. They seem to be forcing people to use simple, less complex passwords.
