Overview
When using the 3rd party Authy application, users see the wrong logo. This article explains how the Auth0 logo in Authy is determined.
Applies To
- Multifactor Authentication (MFA)
- One Time Password (OTP)
- Authy
Cause
Auth0 does not control the logo used by Authy. It uses a Google image search based on the issuer name, which may not be reliable: See Adding custom logos in the Authy app for more details.
Solution
The issuer’s name should be either the tenant’s name or the friendly tenant name if configured. If needed, the tenant’s friendly name can be changed in the tenant’s settings to improve the image search results Authy uses. See Tenant Settings for more details.
Here is the OTP URL structure that Auth0 will generate for the QR code:
otpauth://totp/<tenant_name>:<users_email_address>?secret=<secret_here>&issuer=<tenant_name> &algorithm=SHA1&digits=6&period=30
