Hi @HungBI ,
Do you mean that you want to hide microsoft sign in check box when you login to Power BI ?
I think you can select "Yes" to reduce the number of times you asked to sign in. Next time you open Power BI website, Power BI will sign in the last account you signed in.
You can save the account and password in your browser and next time you want to sign in this account agian, you just need to enter username.
