Hello Everyone !! Hope you all enjoyed my previous blog. Let’s deep dive in how to implement MFA in PowerApps login screen. Recently I had received many requirements for MFA (Multi-Factor Authentication) in PowerApps login screen.

What is MFA (Multi-Factor Authentication) ?
Multi-factor authentication : In this method user needs to authenticate twice or more than that.

Demo

OK. Now we will see how we can achieve the above demo video.

PowerApps Screen

Here I have created two PowerApps screen using canvas app.
1. Login Screen – User keys in login details.
2. Application Screen – User will navigate to this screen after successfully login.

User Login

My Login screen consists of Labels, Text inputs and buttons. Follow below steps to create your login screen

  • Add user name label and text input
  • Password label and text input
  • Login button.
  • Create Data Connections
  • Create a SharePoint list to store the user credentials.

  • Add SharePoint list data connection.
  • Also add Office 365 outlook connection to send OTP.
  • Set the Mode of password text input to Password to mask the data.

Formula on Login Button:

If(
!IsBlank(
LookUp(
'User Details',
UserName = TextInput1.Text And UserPassword = TextInput1_1.Text
).UserName
),
UpdateContext({otpGrp: true}),
Notify("Invalid User or Password. Please conatct your System Administrator")
);
Set(
otp,
100000 + RoundDown(
999999 * Rand(),
0
)
);
If(
!IsBlank(
LookUp(
'User Details',
UserName = TextInput1.Text And UserPassword = TextInput1_1.Text
).UserName
),
Office365Outlook.SendEmail(
LookUp(
'User Details',
UserName = TextInput1.Text And UserPassword = TextInput1_1.Text
).UserEmail,
"OTP to login",
"Your OTP is: " & otp
)
);

OTP Section

We will use this section to facilitate our MFA in PowerApps login Screen.

  • Create a group of OTP input, Resent OTP button and Confirm OTP icon.
  • Set visibility of this group to otpGrp.
  • On select of Confirm OTP icon is below formula
If(otp=Value(TextInput3.Text),Navigate(AppScreen),Notify("Ivalid OTP"))

Formula on select of Resend OTP:

Set(
otp,
100000 + RoundDown(
999999 * Rand(),
0
)
);
Office365Outlook.SendEmail(
LookUp(
'User Details',
UserName = TextInput1.Text And UserPassword = TextInput1_1.Text
).UserEmail,
"OTP to login",
"Your OTP is: " & otp
)

Application Screen

Add a success screen to show successful login.

Whoopee !! Our Multi-Factor authentication login screen is ready.

Hi Rakesh,

Thanks for this post. I would like to implement this. Just don;t understand what you mean by the underneath.
– Create a group of OTP input, Resent OTP button and Confirm OTP icon.
– Set visibility of this group to otpGrp.
Appreciate your response
