# MFA 'Do Not Prompt Me Again For 90 Days' Is Not Working in 8x8 Work For Mobile (iOS)

## Symptom

When a user signs in to 8x8 Work For Mobile on iOS and selects the **Don't prompt me again on this device for the next 90 days** checkbox, they are still prompted for MFA (multi-factor authentication) for every login. ![](https://cdn.us.document360.io/e3a59e39-abd3-4423-964c-0a4008dc5673/Images/Documentation/29158?sv=2026-02-06&spr=https&st=2026-11-03T23%3A24%3A28Z&se=2026-11-04T00%3A24%3A28Z&sr=c&sp=r&sig=zpPSpvNeeWkgBl5LEq4CYO3YudqwpkQFJJ2YygRqkLs%3D)

## Applies To

- Multi-Factor Authentication
- 8x8 Work for Mobile
- iOS

## Resolution

This behavior is expected due to limitations in the iOS mobile client. Specifically, iOS does not support cookie persistence, which impacts features such as the **Don't prompt me again on this device for the next 90 days** checkbox.
