Does anyone know if rate limiting applies to accounts or tokens?

[Nicolas Bourdages _Ubisoft_]

Rate limiting documentation essentially states that rate limits will apply for API tokens

However, what's not clear is what exactly constitutes a bucket from the perspective of a token or credential. If there are multiple tokens for an account, there is ambiguity

- Is it one bucket per account, meaning that if the allocation is 400 per bucket, an account with 3 API tokens gets a bucket of 400 to share between all credentials?

- Is it one bucket per credentials, meaning that if the allocation is 400 an account with 3 API tokens gets a bucker of 400 for each credential?

That has significant implications for us for service accounts. We connect loads of tools to Jira.
