Uphold login is the secure sign-in process that allows users to access their Uphold account, where they can manage digital assets such as cryptocurrencies, fiat currencies, and precious metals. To log in, users enter their registered email or phone number along with a password. Uphold also supports two-factor authentication (2FA), adding an extra layer of protection by requiring a verification code. The login system includes device and location checks to prevent unauthorized access. By using strong credentials and enabling security features, users can safely access their portfolio, make transactions, and monitor account activity through the Uphold platform.
