+# Linking Multiple Identities
+
+thirdweb Wallets allow users to tie the same wallet address to multiple social identities. Developers can programmatically link additional identities at any point in their user journey.
+
+## Link a new identity
+
+When linking two identities, both identities will now be linked to the same wallet.
