After i upgraded from 19.04 to 19.10, i faced the same problem, even with syncing turned on for my account in Chromium.
Here is the output when the problem still existed: $ snap connections chromium | grep password password-manager-service chromium:password-manager-service - - As suggested i executed the following and passwords/autofill for logins were working again: $ snap connect chromium:password-manager-service Here is the output after the problem was fixed: $ snap connections chromium | grep password password-manager-service chromium:password-manager-service :password-manager-service manual Does this password-manager-service connection persist or do we have to reconnect it everytime? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1848621 Title: [snap] lost all passwords on 19.10 when chromium-browser deb was replaced by a snap To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/chromium-browser/+bug/1848621/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
