Trezor.io/Start® | Begin Your Crypto Device®

The first, and arguably most important, step in **beginning your crypto device** setup is conducting a thorough **physical security checklist** upon receiving your Trezor device. Your **Trezor hardware wallet** ships with specialized **tamper-evident seals** and carefully designed packaging. **You must inspect these seals meticulously.** For the Trezor Model One, this means checking the holographic seal applied over the USB port. Any sign of tampering—rips, creases, adhesive residue, or misalignment—must be reported immediately. For the Trezor Model T, the packaging uses a robust, uniquely-sealed design that disintegrates upon unauthorized opening. This **hardware wallet unboxing** verification confirms that the device has not been physically compromised in transit, a prerequisite for robust **non-custodial security**. If your **crypto assets** are to be protected, the integrity of the hardware must be guaranteed from the factory to your hands. This physical check, detailed at **Trezor.io/Start**, is your first line of defense against sophisticated supply chain attacks. Do not proceed to connect the device until you are 100% certain the physical evidence of the seal is perfect. This diligence is what separates secure **digital asset management** from unnecessary risk.

Additionally, examine the device itself for any marks or scratches. Ensure the included **Recovery Seed** cards are blank and factory-fresh. The successful completion of this **physical security checklist** marks your readiness to transition to the digital setup. Remember, the **Trezor.io/Start** platform prioritizes this manual verification because no software check can replace a careful human eye in validating physical packaging integrity. This commitment to layered security is why the **Trezor hardware wallet** remains a gold standard in **secure crypto access**.

As you **begin your crypto device** journey, it is vital to know the distinction between the **Trezor Model One** and the **Trezor Model T**, as the initialization process varies slightly. The **Trezor Model One** uses two physical buttons for all interactions, requiring you to enter the PIN and verify the **Recovery Seed** using the randomized display shown on your computer screen. This air-gapped PIN entry is a foundational element of its **hardware wallet security**. The **Trezor Model T**, however, features a **color touchscreen**. This allows you to enter the PIN and the **Recovery Seed** directly on the device itself, isolating the input entirely from the connected computer, providing an even higher degree of assurance against advanced malware keylogging. Both models require the subsequent step of connecting to the **Trezor Suite** for firmware installation. The documentation on **Trezor.io/Start** confirms that regardless of the model you possess, the underlying **non-custodial security** principles—specifically the generation and safeguarding of the **24-word Recovery Seed**—remain identical. Understanding these device-specific setup nuances ensures a **secure & smooth crypto access** experience tailored to your chosen Trezor model. Choose the device that best fits your interaction style, but rest assured, both adhere to the same stringent security standards when properly initialized via the **Official Site** instructions.

After completing the **physical security checklist**, the next step in **beginning your crypto device** activation is digital authentication. Connect your **Trezor hardware wallet** and download the **Trezor Suite** application exclusively from the link provided on **Trezor.io/Start**. The **Trezor Suite** is mandatory and performs an automated, proprietary **Genuine Check**. This check is a cryptographic verification that confirms your device contains the correct, factory-signed bootloader and has never been used or initialized before. This process is crucial for preventing sophisticated, post-factory attacks. If the check fails, the software will immediately halt setup, protecting your **crypto assets** from a potentially malicious device. Once authenticated, the **Trezor Suite** will prompt you to install the official **Trezor firmware**. This process installs the operating system necessary for the device to function and manage transactions. **The installation of this firmware is also signed and verified by the Trezor Suite**, ensuring that no malicious third-party code is ever loaded onto your device's secure chip. This combination of physical and digital checks, central to the **Trezor.io/Start** guide, provides the multilayered assurance required for robust **digital asset management** and reliable **non-custodial security**. Only once the firmware is successfully installed and the device reboots is it ready for the PIN and **Recovery Seed** generation phase.

The culmination of the **Trezor.io/Start** process is the generation of your unique **24-word Recovery Seed**. This seed is the mathematical representation of your **private keys** and is the single most valuable piece of information you will ever hold concerning your **crypto assets**. The **Trezor hardware wallet** displays these words on its screen—**never** on the computer—to ensure they are generated in an environment isolated from the internet. Your task, as you **begin your crypto device** initialization, is to meticulously transcribe this **24-word backup** onto the provided physical **Recovery Sheet**. We highly recommend copying it twice, onto two separate sheets, and storing them in geographically separated, secure, and fireproof locations. **Crucially, digitizing this information in any form—photos, cloud storage, password managers, or simple text files—nullifies the non-custodial security advantages of the hardware wallet entirely.** The purpose of the **Trezor hardware wallet** is to isolate the keys; exposing the seed online defeats this purpose. Treat the **Recovery Seed** as you would bearer bonds or physical gold; its recovery power is absolute. The longevity and security of your **digital asset management** depend solely on the physical security and confidentiality of this **24-word Recovery Seed**. Once you have verified the phrase on the device, you have completed the secure **Trezor.io/Start** process and are ready to manage your portfolio with confidence.
