Dear @Gedanggoreng currently streamlit_authenticator has no provisions for sending an email to the user with a forgotten username/password. The widget will return the email associated with the forgotten username/password and you will have to arrange for that information to be sent to the userās email yourself.
How did you resolve this issue ?
I am having the same problem
As mentioned previously - currently streamlit_authenticator has no provisions for sending an email to the user with a forgotten username/password. The widget will return the email associated with the forgotten username/password and you will have to arrange for that information to be sent to the userās email yourself.
Iām getting: āUsername/password is incorrectā every time. Iām printing some variables to have a better understanding, but Iām not able to fix it:
I can share everything because Iām just starting with this. Iām trying to log with:
Login: me@mail.com
Password: 123
config.yaml
credentials:
usernames:
myself:
email: me@mail.com
name: Me
password: $2b$12$AlQ63O8OQMQ0Fu/8/6jyYudiDI2MQtXVgV/m1uffW0PPJ4kNXCwLS
cookie:
expiry_days: 30
key: some_signature_key
name: some_cookie_name
preauthorized:
emails:
- me@mail.com

Hash generator
print(stauth.Hasher(['123']).generate())
Please enter the username i.e. myself, not the email.
It worked, Iām such a newbie 
Thank you.
I got the same error, and for me its because I didnāt put the hashed password in the config.yaml file (running the code doesnāt mean you already stored the hashed password, you need to copy paste it into the config.yaml file)
Let me know, if this helps you 
.
Is it possible to use password only w/o names & username?
No, both of these fields are required at the moment.
Hello, thank you for your amazing streamlit component. I wonder if there is a simple way to automatically log out after some time of inactivity (ex: 30min of inactivity).
Hi @AnthonyBrossault, you are most welcome. That is an excellent idea for a subsequent release, please feel free to add it to the GitHub list of issues and I will try to implement it in the near future. In the meantime, you can try to hack it yourself by clearing the session state variable associated with the authentication object after a set period of time, and removing associated reauthentication cookies saved on the browser. Removing keys from session state should be as straightforward as writing del st.session_state[āauthentication_statusā]. You can read more about clearing the cookies here. To measure the passage of time you can make use of a library such as Streamlit Autorefresh. Cheers.
You can use any Gmail account for this by creating and using and app password to your email account as in the following link (https://support.google.com/accounts/answer/185833?visit_id=638215606016109598-1972104324&p=InvalidSecondFactor&rd=1). Once youāve done it, use the following code:
import smtplib
from email.mime.text import MIMEText
from email.mime.multipart import MIMEMultipart
def send_password_email(sender_email, sender_password, recipient_email, password):
# Gmail SMTP server configuration
smtp_server = 'smtp.gmail.com'
smtp_port = 587
# Email content
subject = 'Secure Password Delivery'
body = f'Your password is: {password}'
# Create a multipart email message
message = MIMEMultipart()
message['Subject'] = subject
message['From'] = sender_email
message['To'] = recipient_email
# Attach the email body as plain text
message.attach(MIMEText(body, 'plain'))
try:
# Establish a secure connection to the SMTP server
server = smtplib.SMTP(smtp_server, smtp_port)
server.starttls()
# Login to the SMTP server with the application-specific password
server.login(sender_email, sender_password)
# Send the email
server.sendmail(sender_email, recipient_email, message.as_string())
# Close the SMTP connection
server.quit()
print('Email sent successfully.')
except Exception as e:
print(f'Error occurred while sending the email: {e}')
# Example usage
sender_email = 'your_sender_email@gmail.com'
sender_password = 'your_application_specific_password_generated by Gmail'
recipient_email = 'recipient_email@example.com'
password = 'password_to_send'
send_password_email(sender_email, sender_password, recipient_email, password)
