Downloading the app and signing in
The Modulr mobile app is available on Apple App Store for iOS and Google Play for Android.
Always make sure you are using the latest version to take advantage of all features as they're released.
Once you've downloaded and opened the app, you'll be asked to review the end user license agreement, once you've done this you'll be asked to sign in.
Who can use the Modulr Mobile app?
Any existing Modulr user can use the the Modulr mobile app. The app contains functionality for Company Cards (if you're using Modulr AP) and Approvals (if you’re using The Modulr Portal).
Getting set up and signed in
- Download the app from your store
- Once downloaded, open the app and accept the terms and conditions
- Choose:
- Modulr Cardholder to access Company Cards
- Modulr Approvals to use the payment approvals features
- Sign in with your usual details (see below * for more details):
- Modulr Cardholder uses your existing Modulr AP sign in details
- Modulr Approvals uses the same details you use to sign in to the Modulr Portal.
- Manage any messages you see regarding accepting push notifications – we recommend you turn these on.
*Signing in
Currently, sign in is by using the same details you use to sign in to Modulr on desktop – you may have different sign ins for Modulr Accounts Payable and the Modulr Portal – you’ll see the appropriate screen to sign in from after selecting the feature you want to use (Modulr Cardholder or Modulr Approvals).

Signing in to Modulr Approvals with Authy
Sign in with your usual Modulr username and password, the same as you use for the Modulr Portal.
You'll be asked to respond to an Authy authentication as you would in the desktop Modulr Portal.
NOTE: It's best to have Authy set up on the same device as you have the Modulr App installed, with Authy push notifications turned on, so you can approve in the Modulr app and respond to the Authy request on the same device.
Once you've completed the Authy authentication in the Authy app, you'll be sent back to the Modulr app where you'll now be signed in.

Signing in with Modulr AP
Sign in with your usual Modulr AP details after selecting 'Modulr Cardholder'. Use your usual MFA method – authenticator app etc to complete the sign in.
Face or fingerprint ID authentication (biometrics)
Once you've signed for the first time with your Modulr username and password, and successfully completed the Authy authentication, you'll be asked if you want to set up biometric authentication (Face or Fingerprint) if your device supports it – we recommend you set this up – you'll avoid needing to complete the Authy request each time you sign in.
Once face or fingerprint ID is set up, this will also be used when making approvals instead of needing to respond to an Authy MFA notification.
You can set up biometric authentication later if you skip it on first sign in – just tap the person icon in the top right to view your profile, where you'll see options to manage biometrics.
