Is your feature request related to a problem? Please describe.
If the page reloads, the user is logged out and can't reconnect easily.

Describe the solution you'd like
To enhance the behavior of a reload fo the website, the browser could store a time limited secure token and reuse it to auto_reconnect. Like what prosody recently made possible: https://modules.prosody.im/mod_sasl2_fast.html

Describe alternatives you've considered
The possibility to use "reuse_scram_keys" is already a great enhancment.
a secure token would be similar in the user experience I guess, but even more secure.
