@dec_hl I am using the account email. I see in MSTDN.JS
['grant_type', 'password']
for /oauth/token.
For this entry in the API docs i found:
"grant_types_supported": [
"authorization_code",
"client_credentials"
],
OAuth API methods - Mastodon documentation
Generate and manage OAuth tokens.
(docs.joinmastodon.org)
Theory: Maybe older server software supports grant_type of "password", but not mine?
