It's the worst. I have used Keeper Security for several years but when I received a replacement phone and tried to log into my Keeper account I was unable to, even when I used my 24 word recovery phrase. I contacted Keeper and they told me there was nothing they could do. So now I can't get to all the passwords I have stored. They really don't care. I'm going back to putting my passwords in a notebook.
I thought it might be a good idea to have password protection as well as the convenience of automatically logging in to a range of websites... with just one password. So I surfed the web, found Keeper Password Manager, and thought I had signed up for a free trial. It was probably my mistake - but it was none too clear - and I found myself paying for a year's subscription. So, to make the most of it, I fed in all the websites in my records - 100+ - got Keeper to enter passwords for them, then found it ponderous (continually feeding in the master keyword), unworkable (the long Keeper passwords failed to override the existing website passwords), and I was in a mess. An email to Keeper failed to bring a response. So, I have spent hours re-installing passwords (Forget Password... you bet) and regaining some independence. Conclusion: Keeper is probably excellent for a business with a lot of valuable passwords but, for a home user, it is a lot of stress and a waste of money. I have now transferred all my passwords to Firefox storage with the exception of four banking passwords which I know and have concealed back-up for.
