To resolve this issue on Chrome I had to delete a saved password for certain InfusionSoft pages. Click the hamburger menu in the top right (three vertical dots) then click “Settings”. In the new tab click “Auto Fill” in the left menu. Click the first option “Passwords”. You can scroll through and find your InfusionSoft saved passwords, or use the search bar if there’s too many. I searched “Infusion” and was shown three InfustionSoft pages with saved passwords. Two of them were signin.infusionsoft.com, so I deleted the other and the problem went away, while maintaining my saved passwords for the InfusionSoft signin pages.
The issue with the asterisks I’ve resolved with this Chrome plugin. See this answer for more details.
