How can i add login and password in my streamlit app …please help

I am no expert but I don’t believe there is any way you can do this with streamlit.

However you can proxy the data through a different web server (say apache or nginx) and set up authentication on that. The following article may help. It does it for Shiny which is like an R equivalent of Streamlit.

well i found a minimalistic and easy way around using “pwd = st.sidebar.text_input(“Password:”, value=”", type=“password”) "…and then putting yout file or code or script within it …It gave me very basic security for my app

Here is a code you can use or adapt:

#!/usr/bin/env python

coding: utf-8

%%

## Simple Login App

import streamlit as st
import pandas as pd

#passlib,hashlib,bcrypt,scrypt
import hashlib
def make_hashes(password):
return hashlib.sha256(str.encode(password)).hexdigest()

def check_hashes(password,hashed_text):
if make_hashes(password) == hashed_text:
return hashed_text
return False

if st.sidebar.checkbox("Login"):
    # if password == '12345':
    create_usertable()
    hashed_pswd = make_hashes(password)

    result = login_user(username,check_hashes(password,hashed_pswd))
    if result:

This is using validation with AD:

import ldap3

class Ldap:
“”“Class for LDAP related connections/operations.”""

def __init__(self, server_uri, ldap_user, ldap_pass):
    self.server = ldap3.Server(server_uri, get_info=ldap3.ALL)
    self.conn = ldap3.Connection(self.server, user=ldap_user, password=ldap_pass, auto_bind=True)

def who_am_i(self):
    return self.conn.extend.standard.who_am_i()

def get_groups(self):
    self.conn.search('dc=fill_this_1,dc=fill_this_2', '(objectClass=group)')
    return self.conn.entries

def get_groups_with_members(self):
    fq_groups = [result.entry_dn for result in ldap.get_groups()]

    groups_with_members = {}
    for group in fq_groups:
        self.conn.search(group, '(objectclass=group)', attributes=['sAMAccountName'])

        if 'sAMAccountName' in self.conn.entries[0]:
            groups_with_members[group] = self.conn.entries[0]['sAMAccountName'].values

    return groups_with_members

def get_members_with_groups(self):
    groups_with_members = self.get_groups_with_members()

    members_with_groups = {}
    for group, members in groups_with_members.items():
        for member in members:
            if not member in members_with_groups:
                members_with_groups[member] = []

            members_with_groups[member].append(group)

    return members_with_groups

if name == ‘main’:
LDAP_URI = ‘misitio.com:389’
usuario = ‘user@misitio.com’
clave = ‘------’
try:
ldap = Ldap(LDAP_URI, usuario, clave)
if ldap:
print(‘Usuario autenticado. Bienvenido {0}’.format(ldap.who_am_i()))
#print(ldap.get_groups())
except ldap3.core.exceptions.LDAPBindError as bind_error:
print(str(bind_error))
except ldap3.core.exceptions.LDAPPasswordIsMandatoryError as pwd_mandatory_error:
print(str(pwd_mandatory_error))

For more robust “enterprise” login that’s simple to use, you can take a look at my Auth0 login component.
