[Python] Error while authenticating a Google account from a Python Script

Im doing an script in Python for an application. If there is any issue related with the main function, it should report it sending an email to an specific user.

I use the next code:

# Configure server and port
smtp_server = "smtp.gmail.com"
smtp_port = 587
from_email = EMAIL_SENDER
to_email = EMAIL_RECEIVER
#password ="xxxx xxxx xxxx xxxx"
password = os.getenv('EMAIL_PASSWORD')

if not password:
print("Error: No se encontró la contraseña del correo en las variables de entorno.")
return

# Create message
subject = f"Alerta"
body = f"Alerta"

msg = MIMEMultipart()
msg['From'] = from_email
msg['To'] = to_email
msg['Subject'] = subject
msg.attach(MIMEText(body, 'plain', 'utf-8'))

try:
server = smtplib.SMTP(smtp_server, smtp_port)
server.starttls()
server.login(from_email, password)
text = msg.as_string()
server.sendmail(from_email, to_email, text)
server.quit()
print(f"Correo enviado a {to_email}")
except Exception as e:
print(f"Error al enviar correo: {e}")


The problem is that i get the next error:

Error al enviar correo: (535, b'5.7.8 Username and Password not accepted. For more information, go to\n5.7.8 https://support.google.com/mail/?p=BadCredentials 5b1f17b1804b1-4406d5bbd5fsm142651745e9.22 - gsmtp')
​

I've tried to use the application password of Google but it doesn't still work.

I've tried the same with an outlook account but kind of the same error. Is there any other way to validate user and password? Or bypass it?
