max length for user password field with "algorithm: auto"?

Symfony 4.3 deprecated the bcrypt algorithm, see UPGRADE-4.3.md:

Configuring encoders using argon2i or bcrypt as algorithm has been deprecated, use auto instead.

So I changed security.yaml to:

encoders:   App\Entity\User:       algorithm: auto

The problem is that, after changing to auto, the hashed string is longer:

'INSERT INTO users (..., password, ...) VALUES (...)' with params[...,"$argon2id$v=19$m=65536,t=6,p=1$d2RhZjVuaWJsSnE0TW5haA$ycOn7EHjPOoBTSa6SHDOBWL2AvwfPNjAstlSTEMmPpU",...]:

SQLSTATE[22001]: String data, right truncated: 1406 Data too long forcolumn 'password' at row 1

This string is 97 characters long, while my password column was 64. I don't find any documentation about the maximum possible length with the "auto" attribute, is it 97? Or it can be more?
