Hi @Mengistu,
You can create and manage your API keys by visiting https://develop.purpleair.com/. More information on using the dashboard is available here: New API Online Dashboard.
If you know the email address you originally got your API keys with, we can also check our database for them. To do so, send an email to contact@purpleair.com with the email address you originally used.
