flask session auto logout in 5 mins

from datetime import timedelta
 app = Flask(__name__)
 app.config['SECRET_KEY'] = 'xxxxxxxxx'
 app.config['PERMANENT_SESSION_LIFETIME'] =  timedelta(minutes=5)
The session will created for each client, seperated from other clients. So, I think the best place to set session.permanent is when you login():

@app.route('/login', methods=['GET', 'POST'])
def login():
    #After Verify the validity of username and password
    session.permanent = True
