V3 Access Tokens
BitGo fixed a bug regarding v3 access tokens. These tokens were causing the JavaScript SDK to fall back to v1 authentication, which doesn't include Hash-Based Message Authentication Code (HMAC) .
Now, tokens created with v3 authentication are prefixed with v2x, ensuring they use v2 or v3 authentication protocols with HMAC.
If you're currently using v3 access tokens, BitGo recommends rotating to v2 or v3 access tokens with v2 or v3 authentication. This enables you to have the added security benefits of HMAC.
