Hello,
Thanks for reading my proposal. I shall do your task in best way possible. I have few years of experience in python. I could help you create a login system with temporary token generator within the code. The database can store the logs of token. Postgresql or Mysql could be used. Free or paid database service depends on the amount of data. Kindly, contact me to discuss this in further detail.
Looking forward to your response!
Best Regards,
Muzammil
