I stopped using 1Password in July 2019 when it stopped working with Safari 13 in macOS Catalina. At that time, I tried Enpass but eventually settled on Bitwarden which I’ve been happily using since. I went Premium about a year ago.
Even though I switched to Bitwarden, I didn’t delete 1Password from my devices, thinking that if Bitwarden didn’t work out that I might want to switch back. I never found a reason to switch back, and I’m glad I didn’t because now with 1Password 8 standalone vaults will no longer be supported.
Since standalone vaults are no longer supported with 1Password 8 I didn’t see any reason to keep it installed on my Mac, iPhone, and iPad. If you’re searching for an alternative, I can highly recommend Bitwarden.
