RSA Authenticator app for iOS users authenticating with OTP on RSA cloud-based services.

Description

Apple released iOS 18.4 on April 01, 2025, introducing a behavior change that affects the use of the RSA Authenticator app on certain iOS devices.

Following the installation of iOS 18.4, the OTP value in the Authenticator app for cloud-based credentials is only visible for two seconds, significantly complicating the authentication process for users.

Solution

On April 01, 2025, RSA released version 4.5.4 of the RSA Authenticator app for iOS on the App Store, which addresses this issue.

It is recommended that users who use OTP for authentication with RSA cloud-based services upgrade to RSA Authenticator app 4.5.4 for iOS before upgrading to iOS 18.4.
