SQLite3 schema#
You can choose any table names, just make sure to define them in the adapter argument. The id columns are not UUID types with the default configuration.
User table#
You can add additional columns to store user attributes.
CREATE TABLE user (
    id TEXT NOT NULL PRIMARY KEY
);
Key table#
Make sure to update the REFERENCES if you change the user table name.
CREATE TABLE user_key (
    id TEXT NOT NULL PRIMARY KEY,
    user_id TEXT NOT NULL,
    hashed_password TEXT,
    FOREIGN KEY (user_id) REFERENCES user(id)
);
Session table#
You can add additional columns to store session attributes. Make sure to update REFERENCES if you change the user table name.
CREATE TABLE user_session (
    id TEXT NOT NULL PRIMARY KEY,
    user_id TEXT NOT NULL,
    active_expires INTEGER NOT NULL,
    idle_expires INTEGER NOT NULL,
    FOREIGN KEY (user_id) REFERENCES user(id)
);
