In 2026, it is virtually impossible to create or log into a Lyft account without a valid phone number, as the service uses SMS-based two-factor authentication for security. If you cannot access your original phone number, your only option is to use the "Find My Account" feature on the login screen. This allows you to enter the email address associated with your account; Lyft will then send a recovery link to that email. Once you click the link, you can follow the prompts to update your profile with a new phone number. If you do not have any phone number at all, you cannot use the app independently. Some travelers use a "VOIP" number (like Google Voice), but many rideshare apps have security filters that block these numbers to prevent fraud. If you are stuck at an airport without a phone, your best bet is to use a public kiosk (if available) or ask a friend to "request a ride for a friend" using their own Lyft account, which allows them to input your name and destination.
