What does Single Sign-On (SSO) authentication mean, and how does it help me? Single Sign-On (SSO) allows you to log in directly from the Portal to Investimental BVB and Investimental Global if you’re already authenticated in your browser, without needing to enter your login details (username and password). It also lets you access the Portal if you’re authenticated in your browser in Investimental BVB, again without needing to enter your login details. Share Twitter Linkedin
