I save my settings to the DuckDuckGo Cloud but my installed 1Password Password Manager doesn't ask me for save the Passphrase into 1Password. Sure there is no Password field.
For now i saved the Passphrase manual into 1Password
secure encrypted Password Safe. But it would be more comfortable, if i put in or generate my Passphrase and 1Password ask me for save it as Login.
Btw I sync my 1Password Safe with my Smartphone and Tablet over WLAN or iCloud/Dropbox. 1Password for iOS and Android offers a fast login feature with 1 Click for Login.
On Desktop i can use 1Password with Browser Plugin in all modern Browsers like Apple Safari, Google Chrome, Mozilla Firefox, Opera, Microsoft Internet Explorer. Then it would be more comfortable to login into DuckDuckGo with only one click like in other services.
At the moment i need to create in 1Password manual the Passphrase as Password and manual search for right item and copy and paste into your form field.
