Alternatives to TOTP-Authenticator

A password generator built by an individual developer (halltape) whose companion project on GitHub is a "Telegram bot for password generation and verification" — the code itself is publicly viewable.

Generates strong passwords that are actually easy to remember and type — a different trade-off than pure random-character generators, useful when you'll need to type the password by hand occasionally.

A straightforward random password generator — request a password and get one back instantly, generated fresh each time rather than pulled from a stored list.

Send your own email address and it tells you whether that address has surfaced in a known data breach — a simple, unofficial Telegram front-end for the "have I been pwned" checking model. Never enter your actual password into it.

Despite the "save" in its username, this bot is a plain password generator with a built-in /help command — tap a button, get a random password, nothing stored.
