所以，基本上，我的python程序是一个客户端，它在启动时连接到数据库以获得一个令牌来继续工作。
现在我的身份验证方法对我来说看起来完全蹩脚，我不满意：

async def create_db_connection():
        while True:
            try:
                conn = await asyncpg.connect(
                    user=C.get_credentials(A.Decrypt(user), "vosPgMa"),
                    password=C.get_credentials(A.Decrypt(password), "vosPgMa"),
                    host=C.get_credentials(A.Decrypt(host), "vosPgMa"),
                    port=C.get_credentials(A.Decrypt(port), "vosPgMa"),
                    database=C.get_credentials(A.Decrypt(database), "vosPgMa")
                )
                return conn
            except Exception as e:
                logging.error(f"\n\tError connecting to the database: {e}")
                await asyncio.sleep(0.7)

# Update last time active
    async def log_off_database(token):
        while True:
            try:
                conn = await B.create_db_connection()
                await conn.execute(
                            'UPDATE "Tokens" SET "Status" = $1, "UsedBy" = $2 WHERE "Token" = $3',
                            'Free', '-', token
                        )
            except Exception as e:
                logging.error(f"Error logging off: {e}")
            finally:
                await B.close_db_connection(conn)
            await asyncio.sleep(9)

我应该如何实现auth过程这样：

• 我的证件没有存储在任何文件存储器里。（包括.env）
