st.secrets
st.secrets provides a dictionary-like interface to access secrets stored in a secrets.toml file. It behaves similarly to st.session_state. st.secrets can be used with both key and attribute notation. For example, st.secrets.your_key and st.secrets["your_key"] refer to the same value. For more information about using st.secrets, see Secrets management.
secrets.toml
Secrets can be saved globally or per-project. When both types of secrets are saved, Streamlit will combine the saved values but give precedence to per-project secrets if there are duplicate keys. For information on how to format and locate your secrets.toml file for your development environment, see secrets.toml.
Example
OpenAI_key = "your OpenAI key"
whitelist = ["sally", "bob", "joe"]
[database]
user = "your username"
password = "your password"
In your Streamlit app, the following values would be true:
st.secrets["OpenAI_key"] == "your OpenAI key"
"sally" in st.secrets.whitelist
st.secrets["database"]["user"] == "your username"
st.secrets.database.password == "your password"
