On Wednesday 4th May 2022 Linden Lab officially announced that they will be Extending MFA Protection to Viewer Login. To start using MFA (Multi-Factor Authentication) you will need to enable MFA for your account found here. Activating MFA provides additional protection against unauthorized usage on your account such as changing your password, performing L$ transactions or changing your payment method etc.
Not everyone will use this but it helps to add an extra layer of protection on your account if you choose to activate MFA. MFA will be coming in the next Beta build for the Firestorm Viewer and other third party viewers may want add this in the near future.
Here is the full blog post…
We are pleased to announce we have added MFA (Multi-Factor Authentication) protection to the Viewer. Recently we added MFA to web login. Now it works with Viewer login as well.
To start using it, you will need to enable MFA for your account on this page: https://accounts.secondlife.com/mfa/status
For more info about how our existing MFA works, see Introducing Multi-Factor Authentication for your Second Life Account and the Knowledge Base Article.
You will need to download and install an MFA-enabled Viewer: https://releasenotes.secondlife.com/viewer/6.5.5.571282.html
When you try to log in with an MFA-enabled Viewer, you will be prompted to enter a token from your authenticator app. If you have chosen to save your password information, a valid token will be saved for 30 days. After 30 days your next login attempt will require another token.
For now, if you try to log in with a Viewer that is not MFA-enabled, nothing will change, and you will still be able to log in without a token. However, if you have opted in to MFA then a token will be required for all Viewer logins beginning in the near future.
