In the Github issue, this feature is more than just disabling an auto-fill – we need the “Never URLs” feature (a blacklist, basically) of locations which never prompt to save logins, nor auto-fill. My specific comment there was:
“In LastPass these are called “Never URLs” just for reference - I as well need these for my work internally at my company. Besides websites that might cause performance issues, we have endpoints which are accessed without using Bitwarden (think RSA tokens) so wish to avoid “do you want to add this website?” every login to select domains and IP wildcards (https://10.12.*/, etc.)”
I have many work intranet sites that are RSA token logins and get annoyed when I’m prompted to save credentials for them, I can’t blacklist the sites and domains.
