Hi everyone

Is there something like that:

username = system.tag.read("[System]Client/User/Username").value

to run from 'scripting' to read session properties in perspective?  
thanks!

See session auth props,

> **[Session Properties | Ignition User Manual](https://www.docs.inductiveautomation.com/docs/8.1/ignition-modules/perspective/perspective-sessions/session-properties#auth-properties)**
>
> Session properties are available for use throughout Perspective Sessions. Sessions of a given project will have the same list of properties, however, the actual values are unique and independent for each running Session.

thanks, but I mean something that allows me to read properties in general from scripting.  
like vision has client Tags, and with system.tag.readBlocking I was able to read..

These props are available through scripting. Perhaps explain your use case and give some more details on what you are trying to do.

You seem to be confusing session properties and tags.

Vision uses client tags as a kind of variable with global project scope. **These are tags**.

Perspective uses session properties for shared values. **These are not tags**.

You can read and write to session properties directly from a Perspective script (but not directly from a gateway script). For example:

```python
	self.session.custom.mySessionProp = system.date.now()

```
