The Login view is used for logging in, as well as giving helpful information you may want to know - such as if there is an update, or critical issue in the software or Second Life/OpenSim servers.
Logging In
Login works similarly to how you would log in via the website or another viewer.
Username
This is also known as legacy name. It may or may not have a last name, in the case of no last name the server sees it as "Resident". You do not have to enter "Resident" in that case, the viewer can work around it.
The viewer can handle name formats such as first last, first.last, and first in the case of "Resident" being the last name.
Password
This is your Second Life/OpenSim password.
Login Location
Currently, this lets you choose between your Home and Last Location. Custom login location is in the roadmap.
Grid
This allows you to choose between grids.
Remember Me
Save your login credentials for faster login next time (password is securely hashed).
MultiFactor Authentication
MFA is supported. If you need to enter your MFA code, you will see a prompt with a text field and submit button. Entering your code and submitting will allow the login to continue.
Save for 30 Days
This checkbox on the MFA prompt will allow you to save a hash of the MFA credentials for up to 30 days.
