# Logging In on Other Devices Luffa accounts support logging in on a new phone using the mnemonic phrase. However, please note that a single account can only be logged in on one mobile device at a time. The account can be online on one PC and one mobile device simultaneously. The mobile device can be linked to the PC through the "linked device" feature, enabling seamless interaction between the two. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
