Disabling the Dashlane extension in Chrome or Edge
Once you have migrated your passwords from Dashlane to 1Password, you should disable the Dashlane extension in order to prevent issues with autofilling by 1Password.
In your Chrome or Edge browser, click on the puzzle piece in the upper right and select 'Manage extensions' , or go to More (three dots)), select Extensions, and then select 'Manage Extensions'.
A new tab will open showing the browser extensions that are installed. Click on the slider to disable the Dashlane extension.
Then, restart your browser and 1Password should be the default password manager and autofill passwords.
