As a long-time LastPass user and advocate, it took a lot for me to decide to abandon ship. It was not a breach, or even lack of transparency about it that convinced me. When I learned that not only is my vault compromised in the hands of unknown actors, but that several fields, like the URLs, were stored unencrypted by LastPass. That was the last straw for me, even though I have been using a unique, strong Master Password. I have decided to migrate to 1Password. Its features are equal or superior to LastPass. It has the browser extensions and mobile apps that my family needs. Once migrated, I started changing all my critical passwords, starting with email and financial apps. Changing the passwords is the most brutal part of this process.
