Hi @divimundo,
The timescale cannot be changed, it is provided for convenience when admins frequently logging in from a trusted device only wish to confirm their 2FA code monthly rather than every time.
If you have this feature enabled but are logging in from a different location for <24 hours, you could ensure all browsing data is deleted once you’re done to remove the cookie.
Allow remembering device for 30 days
When this option is enabled, users can click a checkbox to remember their device for 30 days. This sets a cookie unique to their device that will allow them to log in without using 2FA from that device and browser. This feature is for convenience, but it is less secure than requiring 2FA for each login.

Many thanks,
