Under certain circumstances, Coinbase will only process password reset requests from devices that have been previously authorized to access your account. In the interest of keeping your account secure, Coinbase may delay the processing of password reset requests for 24 hours if the request originates from a new device. This can only be bypassed by resetting your password from a previously verified device. 

As a security precaution, if you reset your password from a new device, you won’t be able to send crypto from your account for up to 48 hours. To avoid this restriction, request a password reset from a previously authorized device.

Note: Coinbase Support is unable to expedite this waiting period.
