Source: Reddit: 2024.09.18 Tempads of TVA in MCU are a security disaster.

In Deadpool & Wolverine, as well as in Loki Season 1, all you got to do to travel illegally across multiple timelines is to snatch a tempad from one of the TVA agents. Like if I were designing such a system, I would have probably put in measures to deactivate a tempad remotely from their admin console or something. It hard to believe someone as intelligent as Kang wouldn’t have thought of this.
