Abstract: Methods, systems, and/or devices for providing a frictionless login experience are described herein. In one aspect, a user is allowed to log into a first service using an account associated with a second service by providing the first service with an identifier, such as an email address or phone number. The second service authenticates the user based on the identifier and other information stored on the user's device. Accordingly, the user does not need to enter a password or other confidential information.
