# Existing Tags

Tag’s can grab the token value from the field or generate a value and either pass it on (in case of {apiKey}) or perform some operation such as encryption and then pass it to the field where the tag resides.

```
{apiKey}  
{timestamp}  
{generateNumbers4}  
{generateNumbers5}  
{generateNumbers6}  
{generateNumbers7}  
{generateNumbers8}  
{base64_encode | YOUR_KEY} this form can be used for different functions with multiple values which can be used to combine multiple authentication methods into one token.
```
